My tank went to my family's automotive shop in Cedar Park, Honest1. During the move, a vlamingii tang's tail got caught in a net, and after a few days it became evident that his caudal were ripped. The tail completely fell off after a few days and I figured the fish was a goner. It is still alive two weeks later. It didn't eat for a few days after the tail fell off but is back to eating like a pig as before. Will the tail grow back? It seems to have formed a nub on the end.

Thanks in advance.
