What Is This?

[Betta91]

I bought 2 koi angelfish about three months ago from a private breeder. I noticed when I first got them that one of them has a very wierd looking anal fin. I'm not sure if this is a deformity or what....

here's a picture of it compared to the second angel....the one with the deformation is in the back.

and here it is alone....a little better quality

Yeah it's just deformed. This happens a lot now of days. People keep inbreeding fish until deformities occur. ALso wholesalers often keep young angels in small tanks as they grow out, causing even more deformities. I have a Leopard Gourami that was given to me free by the LFS because he was deformed. He is missing most of his top fin. I'll post a picture soon but this stuff happens all the time.
