no.. this fish is on sale from one guy in our country.
in my thought, this fish is not so tough or aggressive enough, as u can see, it can live with other fishes in the same tank.

as i knew, aimara is much more aggressive, they need to keep alone in the tank. am i right ?

anyway i am thinking, if i want to buy it or... so pls help to ID this wolf fish. tks
