Betta splendens is often referred to as Fighting Fish or Siamese Fighting Fish since it has been bred over the years to be both colorful and combative, especially towards other males. As such, only one male Betta should be kept in an aquarium. However, smaller and shorter-finned - though often equally as colorful - females may be housed together with caution. The Betta should be housed with peaceful fish that will not nip at the Betta's glorious, flowing fins.
An ideal environment for the Betta fish is a well-filtered aquarium that holds a steady temperature of between 75° and 86°F. Though the Betta is often sold in small bowls in department stores, for best care, Betta splendens should be kept singly in aquariums of at least 1 gallon. It also prefers a variety of hiding places amongst the foliage of freshwater plants.
"Betta splendens" can be bred in the home aquarium. For breeding purposes, males and females can be temporarily housed together. Once laid by the female, the eggs are placed inside a bubblenest and tended by the male Betta splendens. Fry appear in about 24 hours and must be fed very small food initially, such as crushed or powdered flakes and newly hatched brine shrimp. Fry will also take finely chopped hard-boiled egg yolk.
