I asked the owner of a local pet store i go to, a couple months ago when I got my common wolf if any tank mates are viable and he said he never found a tank mate that worked with common wolfs. I asked him about the electric catfish and hes skeptical about putting it with a wolf. Would the shock be enough to kill the wolf? The wolf wouldn't be able to kill the catfish he said but visa versa is likely he thought. Thanks.
