Lionfish are among the most spectacular—and potentially hazardous—predatory fish kept in marine aquariums. With elaborate fan-shaped pectoral fins, long dorsal spines, bold stripes, and a slow, almost hovering swimming style, they can become dramatic centerpiece fish in a carefully planned saltwater tank.
The best-known species is the Red Lionfish (Pterois volitans), a large member of the scorpionfish family Scorpaenidae. Several smaller species, including dwarf lionfish in the genus Dendrochirus, are also popular with marine aquarists.
Lionfish are relatively hardy once established, but they are not typical community fish. They are ambush predators capable of swallowing surprisingly large tank mates, and their dorsal, pelvic, and anal spines contain venom capable of causing a painful sting.
For these reasons, successful lionfish keeping depends on three things above all: adequate aquarium size, careful tank-mate selection, and respect for the venomous spines.

🦁 What Is a Lionfish?
Lionfish are venomous marine fishes belonging to the scorpionfish family.
The term is commonly applied to species in genera including:
- Pterois
- Dendrochirus
The Red Lionfish, Pterois volitans, is the species most people picture when they hear “lionfish.”
It has a striking pattern of:
- Red
- Brown
- White
- Cream
- Dark vertical bands
Its enormous pectoral fins spread outward like fans, while a row of long dorsal spines gives the fish its unmistakable silhouette.
Although this ornate appearance may seem decorative, many of these structures play important roles in defense and hunting.
🌊 Where Do Lionfish Come From?
Lionfish are native to tropical waters of the Indo-Pacific, although the exact natural distribution differs among species.
The native range of Pterois volitans extends across a huge area of the Pacific and eastern Indian Ocean.
Wild lionfish inhabit environments such as:
- Coral reefs
- Rocky reefs
- Lagoons
- Reef slopes
- Caves
- Ledges
- Wrecks
- Other structured marine habitats
Many remain close to cover during the day and become more active as lighting decreases.
Their natural habitat provides a useful model for aquarium design: lionfish need open areas for movement but should also have caves, overhangs, and shaded retreats.
🌎 Lionfish in the Atlantic and Caribbean
Lionfish are native to the Indo-Pacific, but Pterois volitans and the closely related Pterois miles have become major invasive predators in the western Atlantic, Caribbean, and surrounding waters.
Their introduction is widely associated with the marine aquarium trade, although the exact history involved more than one possible release or escape.
Once established, lionfish expanded rapidly.
They are highly effective predators and consume many native reef animals, including small fishes and crustaceans.
In areas where lionfish are invasive, they can occur at high densities and place additional pressure on native reef communities.
This ecological problem should never lead aquarists to release an unwanted aquarium lionfish.
Never release any aquarium fish into natural waters.
🔴 Red Lionfish
The Red Lionfish (Pterois volitans) is the best-known aquarium lionfish.
It is also one of the largest.
Wild individuals can reach approximately 18 inches in total length, although many aquarium specimens remain somewhat smaller.
Red Lionfish typically have:
- Red-brown and white vertical bands
- Very long dorsal spines
- Huge fanlike pectoral fins
- Tentacles around the head
- Large mouth
- Broad head
- Slow, deliberate movements
Because of its eventual size and predatory feeding behavior, this species requires a substantially larger aquarium than dwarf lionfish.
🪶 Popular Types of Lionfish
Several lionfish species appear in the marine aquarium trade.
Red Lionfish — Pterois volitans
The classic large lionfish.
It can grow to approximately 18 inches and requires a large aquarium.
Broadbarred or Antennata Lionfish — Pterois antennata
This beautiful species has long pectoral rays, prominent head tentacles, and reddish-brown banding.
It remains much smaller than P. volitans, reaching roughly 8 inches.
Radiata Lionfish — Pterois radiata
Also known as the Radial Firefish or Clearfin Lionfish, this species has striking dark body bands and pale horizontal lines extending toward the tail.
It reaches roughly 9–10 inches.
Fuzzy Dwarf Lionfish — Dendrochirus brachypterus
One of the most popular smaller lionfish.
It reaches approximately 6–7 inches and comes in several color forms, including reddish, brown, and yellow individuals.
Zebra Lionfish — Dendrochirus zebra
The Zebra Lionfish is another smaller relative, although it can become larger than the Fuzzy Dwarf.
It has reddish coloration, dark body bands, and dramatically patterned fins.
📏 How Big Do Lionfish Get?
Adult size depends heavily on species.
| Species | Approximate Maximum Size |
|---|---|
| Red Lionfish (Pterois volitans) | Up to about 18 inches |
| Antennata Lionfish (Pterois antennata) | About 8 inches |
| Radiata Lionfish (Pterois radiata) | About 9–10 inches |
| Fuzzy Dwarf Lionfish (Dendrochirus brachypterus) | About 6–7 inches |
| Zebra Lionfish (Dendrochirus zebra) | Can approach 10 inches |
This enormous variation makes species identification essential.
A juvenile Red Lionfish may look small enough for a moderate aquarium when purchased, but it can eventually become several times that size.
Always plan for the adult fish.
🏡 Lionfish Tank Size
There is no single minimum aquarium size for all lionfish.
A full-sized Red Lionfish requires substantially more space than a Fuzzy Dwarf Lionfish.
As practical starting points:
- Fuzzy Dwarf Lionfish: around 50 gallons or larger
- Smaller Pterois species: roughly 70–90 gallons or larger
- Adult Red Lionfish: approximately 120–125 gallons or larger
More room is advisable when keeping multiple large fishes.
Aquarium dimensions matter as much as total volume.
Lionfish have broad pectoral fins and need enough width to turn comfortably without constantly brushing against rockwork.
🪨 Setting Up a Lionfish Aquarium
A good lionfish aquarium should combine large open areas with substantial structure.
Useful features include:
- Live rock
- Caves
- Overhangs
- Ledges
- Shaded retreats
- Open swimming areas
- Securely positioned rockwork
- Strong biological filtration
Avoid creating a narrow maze of sharp rock through which a large lionfish must squeeze.
The fish’s broad fins need clearance.
At the same time, provide at least one dark or shaded area where the lionfish can retreat during bright periods.
🌙 Are Lionfish Nocturnal?
Lionfish are often particularly active during dusk, nighttime, and other low-light periods.
Some species spend much of the day resting:
- Under ledges
- Inside caves
- Against rock faces
- Near shaded structures
As the lights dim, they may begin cruising through the aquarium looking for food.
Captive lionfish frequently adapt to their owner’s schedule and may become active whenever feeding is expected.
A fish hanging nearly motionless beneath an overhang during the day is not necessarily sick.
🍽️ What Do Lionfish Eat?
Lionfish are carnivorous predators.
Wild prey can include:
- Small fish
- Shrimp
- Crabs
- Other crustaceans
Aquarium lionfish should receive a varied diet of appropriately sized marine foods.
Good choices can include:
- Shrimp
- Prawn
- Squid
- Scallop
- Silversides
- Marine fish flesh
- Mysis shrimp for smaller species
- Other suitable marine-origin meaty foods
Variety is important.
Feeding only one food indefinitely can create nutritional deficiencies.
🐟 Do Lionfish Need Live Feeder Fish?
No.
A healthy lionfish can usually be trained to accept dead or prepared meaty foods, and this is preferable for long-term aquarium care.
Live feeder freshwater fish are especially poor choices.
Common feeder fish may provide inappropriate nutrition and can introduce:
- Parasites
- Bacteria
- Disease
- Nutritional imbalances
When acclimating a reluctant lionfish, aquarists sometimes use feeding tools to make a piece of appropriate marine food move as if it were alive.
The goal should be to transition the fish onto a varied diet of safe, nutritious marine foods.
🍤 Feeding a New Lionfish
Some newly imported lionfish refuse nonliving foods initially.
Patience is important.
Helpful foods may include:
- Whole marine shrimp
- Mysis
- Small marine fish foods
- Pieces of seafood moved gently in the water
Avoid repeatedly overfeeding the aquarium simply because the fish does not respond immediately.
A healthy lionfish may take time to recognize unfamiliar foods.
Once the fish begins accepting prepared meals, continue offering variety.
⏰ How Often Should You Feed a Lionfish?
Adult lionfish generally do not need to be fed heavily every day.
Their predatory lifestyle is very different from that of constant plankton feeders such as Anthias.
Several appropriately sized meals per week may be adequate for many healthy adults, depending on:
- Species
- Size
- Age
- Body condition
- Meal size
Juveniles may need food more frequently.
Avoid feeding until the abdomen becomes extremely distended.
Lionfish can be enthusiastic eaters and may continue accepting food beyond what is ideal.
⚠️ Do Not Overfeed Lionfish
Overfeeding is a common mistake.
A lionfish’s large mouth and impressive feeding response can make it tempting to offer another shrimp—and then another.
Chronic overfeeding may contribute to:
- Obesity
- Poor water quality
- Excess waste
- Nutritional imbalance
- Long-term health problems
A healthy lionfish should look well fed without appearing continuously bloated.
😮 How Do Lionfish Hunt?
Lionfish are highly effective ambush predators.
Rather than racing after prey at high speed, they often approach slowly.
The enormous pectoral fins can help:
- Corner prey
- Block escape routes
- Direct small fish
- Conceal the predator’s exact movement
When the prey is close enough, the lionfish rapidly expands its mouth and creates suction that pulls the animal inside.
This happens remarkably quickly.
An aquarium fish that appears far too large to swallow may still disappear if the lionfish can fit it into its mouth.
🐠 Lionfish Tank Mates
The most important tank-mate rule is:
If the lionfish can swallow it, assume that eventually it may.
Suitable companions need to be:
- Too large to eat
- Not aggressive fin nippers
- Compatible with marine water conditions
- Unlikely to attack the lionfish
Possible companions in appropriately sized aquariums may include certain:
- Larger tangs
- Rabbitfish
- Large angelfish
- Larger wrasses
- Larger groupers with caution
- Other suitably sized predatory marine fish
Every combination should be evaluated according to adult size.
A fish that is safe today may become prey later—or the reverse.
⚠️ Lionfish Tank Mates to Avoid
Avoid small fish such as:
- Goby Fish
- Small Clownfish
- Blue Chromis
- Small damselfish
- Firefish
- Small cardinalfish
- Small wrasses
- Blennies
- Tiny anthias
Ornamental shrimp are also at high risk.
Lionfish are predators, not bullies. They may coexist peacefully with a small fish for weeks before eventually swallowing it.
Peaceful behavior should never be mistaken for permanent compatibility.
🦐 Can Lionfish Live With Shrimp?
Generally, ornamental shrimp should be considered potential prey.
A large cleaner shrimp may temporarily coexist with some individual lionfish, but there is always a risk.
Wild lionfish naturally consume crustaceans.
Smaller lionfish species such as the Fuzzy Dwarf may actually show a particularly strong preference for shrimp and other crustaceans.
If keeping valuable ornamental shrimp is a priority, a lionfish is usually a poor choice.
🪸 Are Lionfish Reef Safe?
Lionfish are often described as reef safe with caution.
They generally do not eat coral.
They are therefore compatible with many:
- SPS corals
- LPS corals
- Soft corals
- Anemones
The problem is the other animals living in the reef.
Lionfish may eat:
- Small reef fish
- Ornamental shrimp
- Small crabs
- Other mobile invertebrates
Therefore, a lionfish can be completely safe for your Acropora while being disastrous for your gobies and shrimp.
🪸 Do Lionfish Damage Corals?
Lionfish do not normally feed on coral tissue.
However, a large specimen can occasionally brush against corals while moving through a cramped aquarium.
Their broad fins make adequate swimming space especially important.
A reef tank containing a lionfish should therefore be aquascaped with:
- Wide passages
- Open areas
- Stable coral placement
- Plenty of clearance around sharp structures
🦂 Are Lionfish Venomous?
Yes.
Lionfish possess venomous spines used for defense.
In the commonly encountered invasive Pterois species, venom-bearing spines are found in the:
- Dorsal fin
- Pelvic fins
- Anal fin
The large pectoral fins themselves are not the venom-delivery structures.
Lionfish do not generally swim around actively attacking people with their spines.
Stings usually occur when a person accidentally contacts the fish or attempts to handle it.
☠️ Are Lionfish Poisonous or Venomous?
Lionfish are venomous, not poisonous in the usual biological sense.
The distinction is:
- Venomous: toxin is delivered through a structure such as a spine
- Poisonous: toxin causes harm when the animal is eaten or touched in another manner
Lionfish venom is associated with specialized defensive spines.
The flesh itself is not made poisonous by those venomous spines.
For aquarium keepers, however, the practical message is simple: never handle a lionfish casually or place your hands near its spines.
🩹 What Happens if a Lionfish Stings You?
Lionfish stings can cause intense pain and may also cause swelling and other significant symptoms.
A sting should be treated seriously.
Avoid handling the fish directly and arrange aquarium maintenance so your hands do not come close to the spines.
If a sting occurs, established first-aid guidance recommends hot—not scalding—water immersion, and medical evaluation may be appropriate, particularly when symptoms are significant, persistent, or concerning.
Because individual reactions vary, urgent symptoms should receive prompt medical attention.
🧤 Safely Maintaining a Lionfish Aquarium
The safest approach is to minimize direct contact.
Useful practices include:
- Know where the fish is before placing a hand in the aquarium
- Use long aquarium tools whenever practical
- Avoid trying to catch or restrain the fish by hand
- Never deliberately touch the dorsal spines
- Move slowly while servicing the aquarium
- Make sure other household members know the fish is venomous
Lionfish often become accustomed to people and may approach during maintenance because they associate the aquarist with food.
That familiarity does not make the spines safe.
🕸️ Moving a Lionfish
Moving a lionfish requires more caution than moving an ordinary aquarium fish.
Long spines can become caught in conventional nets, creating risks for both the fish and the aquarist.
When a lionfish must be transferred, the priority should be maintaining distance from the venomous spines and avoiding unnecessary handling.
If you are inexperienced with venomous marine fish, getting assistance from an experienced marine aquarist or aquarium professional is safer than improvising.
💧 Lionfish Water Parameters
Lionfish thrive in stable tropical marine conditions.
A useful general range is:
- Temperature: 75–80°F
- pH: 8.1–8.4
- Specific gravity: 1.023–1.026
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Keep appropriately low
For reef aquariums, many aquarists maintain salinity near natural seawater levels around 1.025–1.026 specific gravity.
Lionfish are reasonably hardy once established, but they should never be exposed deliberately to poor water quality.
🧹 Filtration for Lionfish
Lionfish can create a substantial bioload.
They eat large protein-rich meals and produce correspondingly significant waste.
Strong filtration is therefore important.
A suitable system may include:
- Efficient protein skimming
- Biological filtration
- Mechanical filtration
- Adequate live rock
- Good circulation
- Regular water changes
Remove uneaten pieces of seafood promptly.
A shrimp hidden behind the rockwork can decay rapidly and contribute to deteriorating water quality.
🌊 Water Movement
Moderate reef-style circulation generally works well.
Lionfish are capable swimmers but usually do not need to spend their lives fighting extremely intense current.
Ideally, provide:
- Good overall circulation
- Strong surface gas exchange
- Moderate open-water flow
- Quieter areas beneath ledges and behind rockwork
Dwarf species in particular may spend considerable time resting around sheltered structures.
💨 Oxygenation
Good oxygenation is important in any predator aquarium.
Lionfish tanks often contain:
- Large fish
- Heavy feeding
- Significant biological waste
All of these increase demands on filtration and oxygen.
Surface agitation, protein skimming, and appropriately sized circulation pumps can help maintain good gas exchange.
🌙 Fuzzy Dwarf Lionfish Care
The Fuzzy Dwarf Lionfish (Dendrochirus brachypterus) is one of the best options for aquarists who want lionfish behavior without housing a full-size Pterois volitans.
It reaches around 6–7 inches.
Color forms can include:
- Red
- Brown
- Rust
- Yellow
The species naturally feeds heavily on small crustaceans.
A tank around 50 gallons or larger provides a useful starting point for an adult.
Fuzzy Dwarf Lionfish still have venomous spines and are fully capable of eating small fish.
“Dwarf” does not mean harmless.
🦓 Zebra Lionfish
The Zebra Lionfish (Dendrochirus zebra) is another beautiful smaller lionfish.
It has:
- Reddish body coloration
- Bold dark bands
- Long dorsal spines
- Patterned fins
The species can grow larger than the Fuzzy Dwarf, potentially approaching approximately 10 inches.
It inhabits coral, rock, rubble, lagoons, and reef environments and often shelters in caves.
Like other lionfish, it is venomous.
⚪ Radiata Lionfish
The Radiata Lionfish (Pterois radiata) is particularly striking.
It has:
- Dark red to brown body bands
- Pale horizontal lines
- Long isolated dorsal spines
- Elegant pectoral rays
It reaches around 9–10 inches.
Wild Radiata Lionfish feed heavily on small crabs and shrimp and often remain beneath ledges during daylight.
This species is generally less commonly offered than the Red Lionfish but can make an impressive predator-tank centerpiece.
🪶 Antennata Lionfish
The Antennata Lionfish (Pterois antennata) reaches around 8 inches and has especially dramatic head tentacles and pectoral fins.
Wild fish feed largely on:
- Shrimp
- Crabs
They commonly hide beneath rocks and coral formations during the day and become active after dark.
Their smaller size makes them easier to accommodate than Pterois volitans, although they still require careful handling and tank-mate selection.
❤️ Lionfish Lifespan
Lionfish can be long-term aquarium residents.
FishBase records the Red Lionfish at a maximum reported age of approximately 10 years.
Captive lifespan depends on:
- Species
- Diet
- Water quality
- Aquarium size
- Disease prevention
- Avoiding obesity
- Appropriate tank mates
Because a juvenile may remain with you for many years, always choose a tank based on the fish’s eventual adult size.
🩺 Common Lionfish Health Problems
Lionfish can develop many of the illnesses affecting other marine fishes.
Potential concerns include:
- Marine ich
- Marine velvet
- Bacterial infections
- Internal parasites
- Nutritional deficiencies
- Poor body condition
- Eye problems
- Damage to delicate fins
Warning signs include:
- Refusal to eat
- Rapid breathing
- Cloudy eyes
- White spots
- Unusual swimming
- Persistent lying on the bottom
- Damaged fins
- Severe weight loss
Do not confuse normal daytime resting with illness.
Evaluate the fish’s appetite, breathing, body condition, and other symptoms together.
🏪 Choosing a Healthy Lionfish
Before buying a lionfish, look for a specimen that:
- Has clear eyes
- Breathes normally
- Holds its fins naturally
- Has intact spines
- Has a full but not bloated body
- Shows interest in food
- Moves normally
- Has no obvious skin lesions
Ask the seller what the fish is currently eating.
A lionfish already accepting nonliving foods is often much easier to establish at home.
Also verify the exact species.
The difference between a 6-inch Fuzzy Dwarf and an 18-inch Red Lionfish dramatically changes the aquarium required.
🧪 Quarantining Lionfish
Quarantine can help prevent marine parasites and diseases from entering an established aquarium.
However, working around a venomous fish adds an extra safety consideration.
A quarantine aquarium should provide:
- Enough space for the fish to turn comfortably
- Hiding structures
- Stable water
- Easy observation
- Equipment that can be serviced without repeatedly approaching the fish
Always remain aware of the location of the dorsal spines during maintenance.
♀️ Male vs. Female Lionfish
Sexing lionfish can be difficult.
Differences depend on species and maturity.
In some dwarf lionfish, males may become:
- Larger
- Broader-headed
- More territorial
Females may remain somewhat smaller.
These characteristics are not always reliable enough to sex juveniles confidently.
Breeders usually need mature fish and experience with the particular species.
🥚 How Do Lionfish Breed?
Lionfish reproduce by releasing eggs into the water column rather than guarding eggs on a nest.
Courtship commonly occurs around dusk or nighttime.
Depending on species, a male and female rise into the water column and release reproductive material.
Females may release eggs contained in gelatinous masses.
The fertilized eggs then drift with ocean currents.
There is no parental care after spawning.
🐣 Raising Lionfish Larvae
Although some lionfish have spawned in captivity, raising the larvae is a specialist challenge.
The larvae require extremely small foods and carefully controlled marine conditions.
Aquaculture may involve:
- Rotifers
- Copepod nauplii
- Artemia at later stages
- Specialized larval tanks
- Precise feeding schedules
- Excellent water quality
For most home aquarists, keeping a healthy adult lionfish is a much more realistic goal than breeding one.
🌍 Why Are Invasive Lionfish a Problem?
Invasive lionfish are highly efficient predators.
In Atlantic and Caribbean ecosystems they consume numerous native reef animals, including juvenile fishes that would otherwise contribute to healthy reef communities.
They also possess several characteristics that help invasive populations thrive:
- Broad diet
- High reproductive output
- Few effective predators in invaded habitats
- Ability to occupy numerous habitats
- Effective hunting behavior
Regional removal programs encourage divers and fishers to harvest lionfish in invaded waters.
This conservation issue should be kept separate from aquarium care: captive lionfish must never be released.
🚫 Never Release a Lionfish
Releasing an aquarium lionfish is environmentally irresponsible and may also violate local laws.
The invasive Atlantic population demonstrates how damaging the introduction of non-native predators can become.
If you can no longer care for a lionfish:
- Contact aquarium stores
- Contact local marine aquarium groups
- Seek another experienced keeper
- Contact public aquariums or appropriate organizations when relevant
Plan for the adult fish before purchasing it.
✅ Are Lionfish Good Beginner Fish?
Lionfish are not ideal first marine fish despite their physical hardiness.
Their challenges include:
- Venomous spines
- Predatory behavior
- Large adult size in some species
- Specialized feeding during acclimation
- Heavy bioload
- Restricted tank-mate options
An aquarist who already understands:
- Marine filtration
- Stable salinity
- Quarantine
- Predator feeding
- Saltwater water chemistry
is better prepared to keep one safely.
A dwarf lionfish can be easier to accommodate than a large Red Lionfish, but it still requires the same respect for venomous spines.
🦁 Is a Lionfish Right for Your Aquarium?
Lionfish are extraordinary aquarium animals.
Their slow hovering movement, ornate fins, intense hunting behavior, and unmistakable appearance make them unlike almost any other marine fish.
They are especially well suited to:
- Large predator aquariums
- Fish-only-with-live-rock systems
- Carefully designed reef tanks without small fish or shrimp
- Experienced marine aquarists
- Aquarists interested in unusual predatory behavior
They are poor choices for community tanks filled with small reef fish.
A lionfish should also never be purchased simply because a small juvenile fits into the aquarium today.
Choose the exact species, plan for its adult size, feed a varied marine diet, maintain strong filtration, select only appropriately sized companions, and always respect the venomous spines.
With those precautions, a lionfish can become a spectacular long-term centerpiece in a marine aquarium.
❓ Frequently Asked Questions
How big do Lionfish get?
Size varies substantially. Red Lionfish can reach approximately 18 inches, while the Fuzzy Dwarf Lionfish reaches around 6–7 inches.
What size tank does a Lionfish need?
It depends on species. A Fuzzy Dwarf may be maintained in roughly a 50-gallon-or-larger aquarium, while an adult Red Lionfish needs a much larger tank, typically around 120–125 gallons or more.
Are Lionfish venomous?
Yes. Lionfish have venom-bearing defensive spines capable of causing painful injuries.
Are Lionfish poisonous?
Their primary human hazard is venom delivered through spines, making them venomous rather than poisonous in the usual biological sense.
Do Lionfish attack people?
They are not generally aggressive toward humans. Stings usually occur through accidental contact or improper handling.
Are Lionfish reef safe?
They generally do not eat coral, but they may consume small fish, shrimp, and other mobile animals. They are therefore best described as reef safe with caution.
Do Lionfish eat clownfish?
A lionfish may eat a clownfish if the clownfish is small enough to swallow.
Can Lionfish live with shrimp?
Ornamental shrimp are risky tank mates because crustaceans form part of the natural lionfish diet.
What do Lionfish eat?
They eat meaty marine foods such as shrimp, squid, scallop, marine fish flesh, mysis, and other appropriately sized animal foods.
Do Lionfish need live food?
No. Many can be conditioned to accept thawed or other nonliving marine foods, which is preferable for long-term care.
How often should you feed a Lionfish?
Healthy adults generally do well with several appropriately sized meals per week rather than constant heavy feeding. Juveniles may require more frequent meals.
Are Dwarf Lionfish venomous?
Yes. Dwarf species still possess venomous spines.
Can Lionfish live together?
Sometimes, depending on species, aquarium size, and the relative sizes of the fish. Cannibalism is possible if one lionfish is substantially smaller than another.
How long do Lionfish live?
Red Lionfish have a maximum reported age of approximately 10 years, and a properly cared-for aquarium fish can be a long-term commitment.
Why are Lionfish invasive?
Red Lionfish and Devil Firefish became established outside their native Indo-Pacific range and spread through western Atlantic and Caribbean ecosystems, where they prey heavily on native reef animals.
