Ok so my tank is a standard 55 gallon tank with, 8 tiger barbs, 1 opline gourami, 2 black mollies, and 2 rainbow sharks would it be possible to add 2 firemouths to the tank. It is planted.
Your rainbow sharks are a problem. Are these FH's going to be male and female? If they breed, your sharks will be in trouble. I find it risky to mix the gourami in there as well.
