Hi There, Just wondering if this ever happened in your tanks, I've had a Linckia Laevigata For the past four months, everything seems to be doing fine till one day (seven weeks ago) mi linckia disappeared in the biggest rock of my tank, it's about 160 pounds, so moving it seems impossible, finally today I move the rock in search for the linckia, but, she wasn't there, I search all over the rockwork for it without success, I have a 200 gl DT with a 50 gl sump, I don't have any fish that could ate her, is it possible that my peppermint shrimp ate her? I have four of them. Is it that my CUC is that good?
I check everything once a week, never had a spike in amonia or anything, sps keep growing, lps also growing all fishes ok.
Any thoughts?
