I need help identifying a fish I got for free. One afternoon I went into petco and saw this fish with almost all of his fins bit off and looking like he hadn't had a meal in a very long time, initially I thought he was a silver dollar but he has piranha like teeth, if you have any idea as to what he is please comment, we took him without know what he was so we could do better by him I wish we would've take a before picture to show you the terrible emaciated state he was surrended to petco in but we've been healing his fins and feeding him flakes and blood worms and he seems to love both. Thank you for any help in advance
