Do you think its pecktoral fin will grow back again? I just notice when I got him at home that he had such a big bite almost into the bone. (sorry for the poor quality shot!)
That is a really bad picture just for the record. I have seen RBP recover from some crazy bites, as long as its not all gone I am sure he will recover. hard to say with this picture. Might not look 100% but it should come back to some point.
