Which one is the most aggressive? And how big does it get? Can you tell me what it's requirements are to induce more feeding and keep it active? Are they boring fish to have etc.
You really are after aggresive fish? Wolf fish are ambush predators so not overly active. But very agressive. People on here have nearly had fingers taken off by a big wolf. If you have a big enough tank a black wolf fish will(iv agitated) rip apart any fish. But some have success with tankmates.
