I did an experiment on a baby crawdad for just that reason. It was less than 1/2 inch and cute when I caught it. I put it in my home aquarium and all was fine at first. Pretty soon I noticed some sculpin missing. Then a cory, then one of my koi had it's entire tail eaten. Although it's claws were still small it's tail was big enough to eat after less than six months. I threw the damn thing out after that in one of my outside lily tanks. Now I have a tailess koi and no more sculpins.

I catch a lot of them and the best bait is dogfood. We just punch a bunch of holes in a can of Old Roy and they swarm it the traps. Any meat, or leftover fish carcass they will pick it clean. Unless I wanted to farm them I would not feed them anything but leftover scraps. I wouldn't want them with live fish either as they stress the hell out of them. They are delicacies in many parts of the world and ours get exported to Norway. Bust one open and suck that head.
