Sam Skinner –
I added Pygmy Cory to my 5-gallon planted tank and they’ve been active and peaceful since day one. They clean the algae on the glass and substrate without causing any stress to other fish. Easy to care for and very cute to watch.

These little fish are perfect for a nano tank. They don’t compete with other fish and seem to enjoy the algae in the tank. I feed them a mix of sinking pellets and algae wafers every day.
