Tank compatibility

Does best kept in a species tank, or kept with peaceful and non-nippy non-anabantoid tank mates. Can be kept in pairs, and if the tank is large enough, several pairs can be kept together.


Will accept most foods including pellet, flake, bloodworm, daphnia and brine shrimp.

Feeding regime

Feed once or twice a day, this fish, as with most Betta species, is prone to constipation and over-eating so its diet must be carefully regulated.

Environment specifics

Needs hiding places on all levels of the tank, tall plants and caves preferred. Does not appreciate a strong current.


A fairly shy Betta without the aggression of its cousin the fancy Betta splendens.


A striking Betta with a black/green body and green dorsal with black bars, the anal, caudal and ventral fins all have a significant amount of red colouration, the anal and caudal fin also have blue. This fish has been hybridised with the Betta splendens and can resemble a plakat Betta splendens to the untrained eye, the colouration and slightly longer and more delicate body shape, however, is a give away.
