Would sea spider eat my corals?
IIRC they enjoy snacking on zoas, you may want to dip a coral or two and see if anything comes off.
Ditto on Jeremy's comments. Check all your zoas.
It depends on the species. Some will only eat one prey species while others are generalists. Reported prey items include various sponges, anemones, other cnidarians, molluscs, polychaetes, echinoderms, tunicates, & more, but actually the preferred food for most species is unknown.
The best known zoanthid-predators are much different looking. They tend to be fairly short, squat, and thick bodied. Usually they're small in comparison to the zoanthids so they like to settle down & stay for a long lengthy meal. Claws tend to be strong & curved, all the better to hang onto the zoanthids. The images on this page show typical zoanthid-feeders --
toss it! it'll eat something or die anyways without whatever it's supposed to eat.
