I bought this little guy about 3 weeks ago. When I got him I am pretty certain that he was all there. I placed him in a 5g fry tank. I have been feeding him regularly and he has been eating fine. He has been on the bottom self so I have not really been looking at him that much. About a week ago I added an upside down catfish. So today I put him in his own 29g and noticed that his tail was missing. Do you guys think that the upside down catfish did it he is about 4in. Could it be and deformity or and old injury ?
