It looks like the end was nipped by a tankmate or constricted by a shed at some point. It's likely to just stay like that or the end will fall off and heal over (be sure to keep it clean if this happens to avoid infection). This is pretty common though so unless you see the damaged area appear to move up the tail/expand or if you see an open wound it's not cause for concern.
