Does anyone use crayfish?

My puffer and Zebra Moray love crayfish. I don't feed crayfish to often cause there freshwater and probably not to healthy. I would like to no if there is a saltwater version of a little lobster or crab that can be found in bait shop/LFS that is healthy for these guys. Important would be availability to.

Well, I'll tell ya what I feed all my aggressive fish. I feed mine: chopped squid, krill, shrimp, and silversides. All my fish love silversides the most but they also really enjoy clam and mussel meat which I feed them occasionally. I have never fed mine crayfish though. I'm sure you could get some mussel meat and it can be good for your fish.
