I don't know how it happened, but we got my albino cory and a bigger cory of the same age to spawn about two weeks ago, and now my 10 gallon has 30 + little cories running around. If I wanted to keep this amount of cories, what kind of tank would I need? If I wanted to sell them, who would I sell them to (I was thinking maybe petsmart or aquabid or a willing buyer from florida who visits this site)?
