Oooh you're right. My snake is a big time rescue. She is blind, I have a hard time getting her to eat anything but worms but I will give it a try if I have a bunch of crayfish in the future. I will ask the garter snake people.
I sure the frog will try it, don't know if it will be too good for...
Yeah I know my fish will eat them. I have fed my catfish plenty of pond-caught crayfish. He eats everything. My piranha is afraid of a little crayfish I put in with him. It's quite funny. Crayfish a third of his size running around trying to pinch him. He did take one of his claws off, though.
