So right now, I've got two crabs that are on the surface. One won't come out of his shell, the other seems to like climbing on me. I think August likes me, but it's hard to tell. My question is, how do I know they're getting enough to eat? Yesterday I put this hopefully healthy crabby food in the tub, I put some organic babyfood with turkey in it, and a blob of fruity baby food (as fruity baby food tastes so good, I have to eat some of it myself.) and also some of this worm poop stuff too. I sometimes used to see little claw marks in the crabby food. The other day it was covered with dirt so SOMEONE probably messed it up. How can I know if they like what I'm giving them?
