This might be a very dumb question but I figured I'd better ask. I have a 29 Gallon Tank that's 78° and lightly planted. The inhabitants include- 1 Dwarf Gourami, 7 Silvertip Tetra, 2 Nirite Snails, and about 6-7 Ghost Shrimp (with new babies!!) What else can I get for this tank other then schooling fish that the Gourami will tolerate? I had purchased a Bolivian Ram at the same time as the Gourami but the Gourami bullied it horribly. He leaves the Tetras alone. What would work with this Gourami? Would a single Angelfish work? Suggestions?
