The Pterygoplichthys gibbiceps albino (Sailfin algae eater) is an excellent cleaner and algae eater. It keeps aquarium glass perfectly clean, clears away food residues and eats all algae. This species is rarely offered for sale in such large sizes. These fish are strong and like to burrow, which means that heavily planted aquariums are less suitable. Ensure there is sufficient swimming space in your aquarium.
