I think I already know the answer to this one, but thought I would get some opinions anyway. The fish is in the 13" to 14" range, and I am working on a 8x4x27 plywood tank for him. The tank is in the early stages and is my first build, so it may be a while before it is running. Other than the obvious female dovii choice, does anyone have any suggestions for something else that may work. A fellow hobbyist suggested that Hypsophrys nicaraguensis may be a possibility. If I want to put anything else in the tank, I should probably start growing it out sooner than later.
