So I was browsing this fish store that I often go to my surprise I saw a wolf fish over a foot long in a tank with a school of blood parrots, some bichir, and a few catfish that were similar in size. As far as I knew about wolf fish at that point tank mates were impossible. The store owner said he never had any aggression issues from the wolf fish, i'm a frequent customer so I trust his info to an extent. To my excitement I bought him and threw him in along with my monsters which are all bigger than him. It's been almost a week with no signs of fighting or injuries and the wolf is eating frozen food well, but I can't say I'm not worried about the wolf killing some of my beloved monsters. I haven't seen a lot of wolf fish community set ups online but the ones i've seen look risky. I believe it's a mala. To keep or not to keep?
