I have two Black Wolves allegedly the same species but I think differently. The first was captured in Venezuela, The second in Brazil, Don't know the exact location.
First is very active and will always sit at the front of the tank. The second is very shy and always hides from me but is however extremely aggressive to other fish irrespective of size. I can't put anything near him.
Apologies for the dirty glass.
