Will Corys clean my tank?
As a small bottom feeder, the corydoras catfish is an extremely efficient cleaner. It will scavenge the leftovers that have sunk to the bottom, cleaning up after messier fish that feed at the surface and midlevel of the tank.
However, Corys do not clear algae from aquarium glass and should not be confused with algae-eating species like plecos (suckerfish!)
Corydoras thrive in well-oxygenated planted aquariums with plenty of shady areas amongst driftwood and rocks. The presence of mid-swimming fish will help to encourage the Corydoras out more often. Corydoras have the ability to breathe air intestinally, so a gap should be left between the water surface and the fish tank hood/lid to allow the Cory to come up to the surface and take air in. It is perfectly normal for a Corydoras to do this many times a day.
