Diet
In the wild it primarily feeds on small aquatic invertebrates such as insect larvae and crustaceans, but in captivity it readily accepts prepared foods like pellets, frozen foods, and live foods.
Community Compatibility
Best kept in a species-only setup or with very small, peaceful fish that will not nip fins or outcompete it, in a calm, heavily planted aquarium.
Good to Know
Betta rubra is a small, strikingly patterned wild betta that’s generally less aggressive than the typical Betta splendens but still appreciates plenty of hiding spots and territories in the aquarium.
Gender Differences
Males display broader black body bars and a more intense red coloration on the fins, while females tend to have paler hues and less sharply defined striping.
