yea thats what i figured. my triggers are very well fed (mostly a wide variety of frozen food and flakes). ive had other people say my triggers will eat them, but ive had my serpant for about 6 months and the triggers have shown no interest in it. my domino has checked out the starfish but only because there was some food on its back. other than that they dont seem to mind that they are even in the tank. i kind of like the starfish and i think i might add 1 more to help do some scavenging and cleaning...since my triggers ate my snails and crabs. although i might try a large hermit crab or two, i heard those are safe as well
