No. Whilst I agree with the comment above in some aspects. Bettas are not murder machines. Not even Plakat bettas which ARE murder machines can be kept with other fish. I've had super aggressive bettas live completely peacefully with all the person above listed as incompatible. I used to keep an outdoor kidde pool with a male and female betta and two huge opaline gouramis. Never once was their any hint of aggression. Its all about tank size. Anything smaller than a 10 gallon for a betta and gourami is a no go. Its all about tank size
