I'm planning on getting a shoal of Corys for my 55 gallon Species only Brichardi tank. In true brichardi fashion, there is a few different fry generations and broods on going in the tank, but I was hoping to get a small shoal of corys to help clean up. I guess the brichardi shouldn't give the corys too much of a hard time while defending their territories. I'll definalty keep an eye on things to see how they do.
