The Ocellaris Clownfish (Amphiprion ocellaris) is one of the most recognizable and widely kept saltwater aquarium fish in the world. Its bright orange body, three crisp white bands, and black-edged fins create the classic clownfish appearance. Just as importantly for aquarists, Ocellaris Clownfish are relatively hardy, readily accept prepared foods, can be bred in captivity, …

Few aquarium fish display as much visual diversity as the Betta. Domestic Betta Fish (Betta splendens), commonly called Siamese Fighting Fish, can have enormous fan-shaped tails, spiky crown-like fins, compact plakat bodies, metallic scales, koi-like patches, solid jewel tones, or combinations of several traits at once. That variety can make Betta terminology confusing. A “Halfmoon,” …

Few aquarium fish have been transformed by selective breeding as dramatically as the Betta. Domestic Betta Fish (Betta splendens) now appear in colors, patterns, fin shapes, and combinations that would be almost unrecognizable beside their wild ancestors. Brilliant metallic coppers, marble-pattern koi, enormous Halfmoon tails, white Dragon Scale bodies, oversized Dumbo fins, and unusually colored …

If your Betta suddenly spreads its fins, pushes out its gill covers, and seems to double in size, you are witnessing one of the species’ most distinctive behaviors: flaring. Betta Fish (Betta splendens) are naturally territorial animals. Flaring is part of their visual threat display—a way of telling another fish, reflection, or perceived intruder that …

When a Betta suddenly floats at the surface, sinks to the bottom, tilts sideways, or struggles to remain upright, many aquarists immediately say the fish has “swim bladder disease.” But the swim bladder itself is not a disease. It is a normal and important organ that helps a Betta control buoyancy and maintain its position …

Breeding betta fish can be one of the most fascinating experiences in freshwater fishkeeping. From watching a male construct his bubble nest to spotting tiny fry hanging beneath the bubbles, the process offers an up-close look at a surprisingly complex form of parental care. Betta fish (Betta splendens) are bubble-nest spawners. Instead of scattering eggs …

Betta fish are often described as hardy aquarium fish, but that does not mean water chemistry can be ignored. Stable, clean water is one of the foundations of good betta care, and pH is an important part of that equation. Fortunately, bettas are relatively adaptable when it comes to pH. You do not need to …

A betta fish with a suddenly swollen belly can be alarming. Sometimes the explanation is relatively simple, such as eating too much at one meal. In other cases, abdominal swelling can be a sign of a more serious problem involving fluid accumulation, infection, parasites, reproductive issues, or an internal mass. The important thing to remember …

Finding your betta fish lying motionless at the bottom of the aquarium or floating near the surface can be upsetting. Before assuming the worst, however, take a moment to observe carefully. Bettas can rest almost completely motionless, sometimes on the substrate, against a plant, or near the water’s surface. A sick betta may also become …
