Earthworms are great as an occasional treat, my fish would happily live off them. But you don't really want them to be making up 100% of your fishes diet. Variety is key for the long term health and wellbeing of your fish.

What would you recommend as a long-term food then my fish is strictly carnivorous usually and I don’t think we need any fruit and the only other thing I’ve ever seen him eat are crayfish

Whole frozen fish if you can find it at your local Asian market. Maybe the occasional frozen small frog. This all depends on the size of your black wolf too. Defrost the fish, and stuff it with pellets for needed vitamins and minerals. The bones, fat (stomach and around the eyes), and scales of the defrosted fish will sustain the wolf properly, and the pellets will ensure it gets the proper vitamins that are not present in dead prey.

You can think about pellet training it for ease of feeding. Remember that these are sedentary ambush predators, so a full rounded stomach can sustain it easily for 1 week, maybe more (again depending on its size).
