There is evidence that the genetic basis for aggression in betta fish is not exclusively sex-linked – a 2019 study found that female bettas of the fighting strain show significantly higher levels of aggression than their female wild-type counterparts, despite the fact that historically only male bettas have been used in fights and thus ...
Swim bladder disease, also called swim bladder disorder or flipover, is a common ailment in aquarium fish.

Siamese fighting fish (B. splendens) are frequently sold in the United States simply as "bettas". As of 2017, around 73 species are classified within the genus Betta.

Celery was probably a typical pet store Betta fish. She was blue with pink tinged-fins, not as iridescent or full-finned as some of her plastic tanked neighbors, but healthy looking enough.
When large numbers of fish, like shoaling forage fish, are in confined situations such as shallow bays, the excretions from the fish encourage this dinoflagellate, which is not normally toxic, to produce free-swimming zoospores. If the fish remain in the area, continuing to provide nourishment, then the zoospores start secreting a neurotoxin ...
The comet or marine betta (Calloplesiops altivelis) is a species of reef-associated tropical marine fish in the longfin family Plesiopidae, most commonly found between 3 and 50 m deep. It is native to the Indo-Pacific Ocean.
Betta pi is of mild importance in the aquarium trade. It is not recommended that it be housed into a community aquarium, not because of its aggressive nature typical of gouramis, but because of its very specific requirements. The water conditions recommendable for Betta pi include 4.0-6.5 in pH, and 18-90 ppm in GH. It requires acidic water ...
A male Siamese fighting fish, Betta splendens, is building a bubble nest. In general, the labyrinth fish are carnivores that eat small aquatic organisms and carrion. Some species will also consume algae and water plants. Most fish are active during daytime, but several African species feed at twilight and night.
