Rosesrblu1 said:Kio, live aquaria doesn't say they eat urchins. They do say they eat coral, tube, worms, sponges, clams. I have 2 sand sifting stars, and they aren't predatory to other inverts.
OP... However,I did a bit more digging and another website. Fresh marine, does say they eat urchins. I would say your star is the culprit.
I have always wanted one, because they are very beautiful, but the cons for me outweigh the pros with this species
