Each Wolf is different some will get along some won't. I had gotten a 10+ Wolf on trade tried to keep it with some bichirs that were longer them him also with some other fish that were also bigger. He immediately attack violently any fish that came within 5" to him. Previous owner said it was peaceful I couldn't keep him with any fish I ended up trading it away.
to me, its a super bad idea. you'll need a hge tank!
