So at my school, we have an amazing ichthyology club and I have been given the opportunity to set up a pearl gourami tank and eventually try breeding them. I would like to set up a heavily planted tank with lots of hardscapes (I believe the tank will be 30-40gal). I want to add some fish that will complement the colors of the gourami pair but also be compatible with them. I really just want to get down a list of possible tank mates to sort through for when I can actually get the fish. For the pearl gourami's, I also wasn't sure whether it would be best to get 1 male and 1 female or if it would be a better idea to get 2 or 3 females for 1 male. I don't want to overstock the tank of course, but any ideas of fish that would be good in a community setting and complement these fish would be highly appreciated!
