Welcome to the forum!
Always nice to have another betta lover around. You should check out the Betta subforum.
Betta are different than other gourami in that they have actually been bred to be more aggressive (they're not called fighting fish for nothing). The wild Betta
species can be kept in male/female groups as they aren't nearly as aggressive as our domesticated B. splendens
; another betta keeper here has lots of wild Betta spp
. LittleBettaFish is her user name; she has some gorgeous tanks and fish. It sounds like wild Betta
are more up your alley than the domesticated ones.
All might be peaceful right now, but don't be surprised if you wake up to a surprise spawn or a dead fish. We're not 100% convinced that it will end in disaster, but most of us are worried for your fishes' safety.
