Pygmy Cory Catfish (Corydoras pygmaeus)

Pygmy Cory catfish are a tiny species of catfish that is somewhat unique among corydoras. While they may not have the most striking colors or pattern they do not behave like more common species. This species spends a fair amount of time swimming around the middle of the tank rather than sticking to the bottom like their larger cousins. However, like other cories they enjoy being in schools of other individuals.
