The Albino Cory are quite hardy and adaptable, very peaceful, and they help keep the bottom of the aquarium clean by eating up leftover foods!

BTW As far as I know, there is no such thing as a 'dwarf' albino cory catfish. Sometimes petstores will tell you they are dwarfs or that they are 'jumbo' pets to get you to pay extra.

But get him some food! He'll like that much better then algae.
