had a choc chip, he like to play the game "knock over snails and suck them" used to feed him shirmp.
now have a brittle (he's a brownish red) and a serpent. feed both shrimp maybe once a week, maybe not. they'll cool, fun to watch. serpent was missing a leg and a half so he was reall fun to watch.
we feed them by first feeding the fish, the stars will come out in hope to get some food. then we make the star come to us, we hold the piece of shrimp in the water and let them take it from our hands, normaly they will rap their arm (or whatever it is) around the shrimp and bring it to their mouth.
hope this helps
