Betta smaragdina(Emerald Betta)

Very similar to Betta splendens but with shorter fins. Males and females are similar, both having reddish bodies with blue-green speckles on the flanks. Both sexes also have two horizontal stripes running from the snout to the tail, but these are most obvious on the females during mating. At other times these stripes become fainter and less distinct.

These fish will hybridise with Betta splendens so it is important to keep the two species separated.


Fish information (behaviour and breeding):

Males are quite aggressive and it is best to only keep a single specimen per tank. In large, thickly planted tanks more than one male might be possible, in which case their threat displays can be observed. The females are tolerant, and one male with two or three females could work well in a quiet community tank.

These fish breed in the same way as Betta splendens, constructing a bubblenest and with the male taking full charge of broodcare.
