female bettas are like them. it depends on the individual fish if they will cooperate with you or not, plus you need to have at least 5 females for a sorority to work (for the bettas, dunno about the gourami). It's a hit and miss and might not be worth a shot if you're putting them with community setup.

Labyrinth fish are... well, labyrinth fish may them be a male or a female.
