I keep plenty of pygmy cories but they like room to swim in. My smallest tank with a pygmy size cory is a 10 gallon,and that is small, for my tastes, as a place for them. This C. habrosus is located in a 29 gallon with a few of his friends and some endlers livebearers.
This group of C. hastatus is shown in a fairly new setup in a 20H. It is a colony of 13 of them in that tank.
Finally this C. pygmaeus is shown along side a Heterandria formosa and is part of the only group that I have in a tank as small as a 10 gallon. A Heterandria formosa is a much smaller fish than a betta so that part of the comparison is not really valid. The 6 cories in the tank work well with the Heterandria though.
