So I am looking to set up a 55 gallon tank, and I was going though what species of fish I want to keep. I know 55 gallons is a small tank for most South and Central American Cichlids. I had to narrow the list down, and I wanted a firemouth. I was doing some research about these fish, and I know they live in Central America. So I want to also keep sword tails with maybe a pair of firemouths. I want to know what other fish I can keep with the firemouths. I want mainly central American fish. Are there any tetras or just any other species of schooling fish from this portion of the world (Mexico, Guatemala, Panama, Costa Rica, El Salvador, Honduras, Belize, Nicaragua) that can live with firemouths. And if anyone has suggestions on bottom feeders.
