One of my angels fell victim to an unknown fin nipper in my tank (flagfish wanted a snack). I've since moved the flagfish to another tank and was wondering if the angel's fins will grow back. Most of his tail is gone as is most if not all of his dorsal. He seems happy and healthy otherwise, not skiddish, swims around with the other angels and he eats a ton like normal. I had him in a seperate 10g after i noticed the damage and treated the tank so he wouldn't get diseased.
