Betta imbellis have a pair of suprabranchial chambers that each house an air‐breathing organ known as the labyrinth apparatus:a complex bony structure lined with thin, highly vascularised respiratory epithelium. The labyrinth apparatus is a morpho‐physiological adaptation that allows the B. imbellis to extract oxygen from air. This adaptation allows these fish to persist in extreme conditions.[3]
Description
Size: 2 inches long.[4]
Distribution
Indonesia, Malaysia, Singapore and Thailand.[5]
Habitat
B. imbellis lives in sluggish bodies of water. This includes rice paddies, swamps, streams and ponds. The substrate is leaf litter and mud.[6]
Conservation status
This species is listed as least concern by the IUCN red list.
It is still threatened by pollution and hybridization with released domesticated Bettas (siamese fighting fish) and other Bettas in the B. Splendens complex.[1]
Diet
Eats terrestrial and aquatic invertebrates in the wild. In captivity they can be fed live or frozen food like Daphnia, Artemia or bloodworms. [7]
Breeding
Males and females can live together outside breeding season, as well as getting together for breeding. Males will build a bubble nest before breeding. After mating the male catches the falling eggs and places them in his bubble nest. In 1–2 days the eggs hatch and continue absorb their yolk sack for 2 days. After that the fry become free swimming. Until this the male cares for them. [8]
Human use
It is found in the aquarium trade. [9]
