I have a 90 gal with 20 gal sump. Currently I am left with a File fish, 2 clowns, yellow watchman goby, cherub angel, hawkfish, LPS corals and rose bubble tip anemones. In the past several months hermits and snails began to disappear then I have had a coral beauty, yellow tang, scopas tang, pearl scale butterfly, brittle star disappear without a trace. I removed most of the live rock into a 29 gal (anything that had a hole in it that could house anything). Then I had an anemone that had split maybe a month earlier disappear without a trace! I took everybody out of the main tank, went through the sand bed and found nothing. Put everybody back in except the live rock still in the 29 gal. I have been in the hobby for 15 years and am totally at a loss. I'm afraid to put any fish in. I would welcome any ideas.
