The little crayfish is doing great. I used a tube to drop a pellet of crayfish food in front of him. I got the food from the fish gal. My cray rushed up to it, felt it all over, then abandoned it. I wonder if he took a couple of nibbles? The snails finished it off in a few minutes, though. I was worried about the big snails getting my little guy, but he climbs over them like rocks. I've seen him sitting on a flake of regular fish food for a long time, working on it. Maybe because he is so little he like the fish flakes best.
I think I have too many snails, and I see eggs on the aquarium walls. I think I will get a few out and return them to the fish gal.
I ordered some long aquarium tweezers.
