i have question. i am trying to put together a fish only aquarium and have an idea of the fish i want but need a secon opinion. the fish are as follows: a clown triggerfish, piccasso triggerfish, emperor angelfish (juv.), a blue hippo tang, and a maroon clownfish. i have been told that it should be fine just keep the fish feed so the triggers dont get hungry. others said you need like a 200 gallon agarium. i am getting all the fish between the 1 and 3 inch range. i have a 55 gallon fish tank. i tore down my reef tank and already have the maroon clown and blue hippo. i want to add the other. please help me out.
