I have two blue Gouramis, and 1 what I think is a female dawf gourami. The dawf has developed a fat belly and is turning colors . I don't know if the blue gourami will breed with the dwaf ? Should I remove them from my community tank ? Worried about other fish eating the young if she does have eggs and if the male will build the nest. I have floating moss balls and fake plants that float.i turned off air stone.
