Yes before I brought it was in with an aggressive shoal of about 20, 6 inch leporinus striatus which were very aggressiveHard to tell for me from that picture and ID-hostile angle. Doesn't look like any of the common ones - eupterus, USD, or a hybrid.
Has the fish been bullied? It has a damaged eye and fin(s).
Yes I'm trying beefing him up on my sis shrimpWell he's definitely not in good shape which make the ID a little harder
