my biology teacher has a five gallon aquarium with like 3-5 goldfish, but it is sooooooo freaking dirty! she said that she wants to put an algae eating fish in their and NOT any snails. what would be good to add to the aquarium? also, i have a 29 gallon with a very small pleco in it, but i know it is going to get really big and want to know what other fish i can add with 2 african cichlids. (i don't like snails very much)
