Those are definitely not the same species
Alex yours is tough to ID from those photos, I know it's difficult but it would be super helpful to get a glimpse of the inner pectorals
Silent, yours is one of three IMO, S. Diabolus, S. Macrochir, or S. Neglecta. Once again, the easiest way to be 100% positive is to check the inner pectorals. Is this the fish you had a thread about recently that was at your lfs?
I am certain these are not the same species.
