I am getting ready to order 4 of these to go in my 55 gallon. I had read that you don't want to keep more than 1 male because they will fight and that you don't want to have 4 of the same type of gourami because they will gang up on the other fish. I was hoping someone with experience in keeping gouramis could let me know if this is true. It just seems strange to me that all the stores I see carry only the male gouramis if this is the case. Now I'm finding sites that say the gouramis could be kept in groups of 4 of the same species but doesn't say anything about keeping males together.
