About the Fish
Betta splendens is a very popular aquarium fish, originally from Thailand. They are colourful, with many varieties, and have relatively low maintenance requirements. They are territorial and were initially bred for aggression and used in gambling. Bettas flare their gill covers (opercula) to appear impressive, to intimidate other rivals, or attract a mate. The males are particularly inclined to fight, being solitary and combative.
Bettas are intelligent and inquisitive, and so require a stimulating environment to flourish. Without this they may become bored and depressed, leading to lethargy and a weakened immune system. Vegetation, rocks, caves, driftwood, and tank ornaments provide crucial enrichment. Floating plants and leaves can help bettas feel more secure, while also giving males an anchor from which to build their bubble nests and facilitate their instinct to claim protective territory.
Betta fish sleep wherever they feel comfortable, including at the bottom of a tank or floating at the top. When asleep, their bright colours may fade, and, when combined with their unusual napping positions, they may appear dead to the inexperienced. They can even sleep out of water on flat surfaces by the edge. This is possible because of the betta's labyrinth organ, a specialised breathing apparatus that allows betta fish to extract oxygen from air rather than from the water using their gills.
