Hi, I recently cycled my new 55 gallon tank and I'm slowly starting to stock it. I currently have 15 harlequin rasbora and 4 praecox rainbow. I'm now looking to add some cories. I was at my LFS yesterday and they had just received a shipment of fish. There were three types of cories that stood out to me. They were the Sterbai, Julii, and Panda. I was just wondering which were your favorite or find to be most interesting/active? I'm looking to get six but from my understanding the pandas are a little smaller so i would probably go with 8 of them. Like I said it's a 55 gallon. I have a white sand substrate. Moderately planted along with some driftwood. I keep my water around 76 degrees.
