I bought a baby senegal from PetsMart forever ago - it was about 2'' at the time, and severly deformed. Found out from a worker that when it came in on the shipment, it had a rubber band stuck around its midsection, which they were able to cut off. I felt sorry for the little bugger, so I promptly bought him. He's now around 5'', and sometimes I wonder if putting him out of his misery would have been a wiser decision. As a whole, he's completely healthy and eats like a horse. His growth rate has been VERY pathetic ever since I got him, and watching him swim hurts a bit. It's very sad looking - his injury is midway down his spine and the back half of his body doesn't move. His head and forebody has to do twice the work to drag the rest of him around. He doesn't let it get him down, and lives normally. I have seen NO change in his condition since I brought him home.
Just some food for thought.
