We have had Otto for almost two years now and he is doing fine. I just love to talk with him and have him swish his tail, especially when we are getting ready to feed him.

BUT......when Helen was doing the weekly cleaning of his water over the weekend, we both noticed that his top fin is gone. Completely gone. He doesn't seem to be bothered by it and is still swimming happily in his bowl, but it makes me worry that we are missing something.

Any ideas or thoughts?
