Link, I just got a chocolate chip star the other day and its doing great! Its an awesome invert to have I think. He kinda moves all around the tank, all around the rock. I think hes still tryin to get a feel for the tank and then he'll probably find a good spot for himself. I highly reccomend getting a starfish though! Good luck!
BTW, my tank is a FOWLR
so I can have the choc chip starfish, they are bad w/ coral though so you cant really put them in a reef tank.
