So im tryin to figure out what other fish to add to my tank. Tank is a 30gal cube. The only fish that is in there now is a small borbonias anthia. I want to add 1 or 2 other rare fish, or some type or schooling fish. But the only schooling fish I can think of for a tank this small is orange lined cardinals. Anyone else have any other options? I dont want anything that is going to dig in the sand either.
