I just got back from the LFS. I picked up a couple of spotted cories for my 29 gallon tank and couldn't resist picking up an odd looking cory to keep them company. He was in the tank with the bronze cories and the lady at the store said she figured he came in the same shipment with them. He's definitely a cory cat, but he's completely black. His fins are grey and have no markings, but his entire body is black except for his stomach which is white like all the other cories. I wish I had a camera to post a picture. Anyone have any idea what he is?
