I have had a Panda Cory for about 4 months now, and bought him a playmate yesterday! I knew they did better in groups, but he has livened up so much just since he has a buddy now. They swim up and down the tank walls together and are always pretty close to one another. I got a Julii Cory... So my main question is, if I get a tank with more bottom space and want to expand my Cory crew could I get one of each variety? (spotted, albino, green emerald, etc?) And would they breed with one another?
