Albino Cory cafish are not algie eaters. They are bottom feeders and will eat food that sinks to the bottom of the tank. Plus, you need atleast 3 of them to be happy, they live in groups.

How many gallons is your tank? (I think you said it was 10 in another post, this way you could get 2 more )

Becareful about what gravel you use, their barbels (I think thats what they're called) can be harmed if your gravel is to sharp or rocky.
