Had this guy for a couple months now, he's about 5 inches...starting to lose more of his black top every week. Just wondering what kind he is...I also have a sibling of his who is completely white and about 3 inches...not sure if that helps the id. Also, he does have some kind of a small deformity on his pectoral fins, seems to be getting better with quality food and water but don't think it will completely heal. Anyways, here are his pics and some of his sibling.
