Hey all! I purchased 4 Pygmy Cory cats about three weeks ago, from my LFS, they were the first fish in a new 10 gallon set up. They have settled in nicely and seem very happy! i called the LFS today to see if they had more Pygmy cats in stock and reserved 2 so i would have a school of 6. Upon returning from picking up the 2nd batch of corys and starting the acclimation process i noticed that i actually have two very different looking catfish. I now believe, after some research, that the first 4 were actually Salt and Pepper corys and the 2nd two are true Pygmy corys. I was wondering if the six of them are sustainable in the 10 gallon or if i need to return the 2 Pygmy and get my hands on two more salt and pepper corys. Thanks for any insight!
