Hi everyone, I have a big natural looking heavily planted tank (64G) in my living room of which I'm very happy. Now I'm looking into the idea of getting a smaller tank in my bedroom with dwarf gourami and neon or cardinal tetra's. I'm not sure if it would be best to get a single male gourami or if he would do better with 2 or 3 females. I'm also wondering what size of tank would be a humane choice. I don't want to put an enormous tank in my tiny bedroom, ideally I'd prefer a 15G but I'm willing to go (a bit) bigger if necessary.
