Get some better pics and I will let you know. I have had all 3 wolves and will be able to help you out. Let it settle in so it isn't stressed and take some nice side shots but not to close or not to far away either.

it's def a stressed out mala guys.
don't know what's the huge problem in solving this.
It's not that clear but the OP's wolf has a dark vertical bar along its body. Plus the unique gill plate. This points to a MALA.
Quick question does well oxygenated water prevent your wolf from coming to surface for air the senegalus polypterus I used to have came to surface for air like every two mins

I believe that wolffish are not airbreathers. Bichirs need to take gulps of air at the surface because they have "lungs" in their bladder.
A good filter will outflow would be good enough for the wolf. They are hardy fish.
These Hoplias are non air-breathers; but Erythrinus and Hoplerythrinus are air-breathers.
I don't know what you have OP to be certain, looks like a mala to me on the surface (anyone remember the Felipe incident?), wouldn't be surprised if it was. Clear under-jaw shot would help.
