I am putting up a Polypterus delhezi tank and someone suggested that Wolf Fish (Hoplias malabaricus) work great with them?
Thanks.NO NO! Forget it! The wolffish will eat him! Also wolffish need lower temperatures.
It could be risky, but I had a wild caught mal with a bichir for months. Never a problem. The bichir would cuddle up to the wold, and the wolf would tolerate it.
Also why would a wolf need lower temps? They are amazon fish.
