Last week I added my second anemone. Just like the first it stayed on the original rock that had a hole for its' foot for a few days. The first one tried different areas in the tank for a few days and then disappeared. The second one disappeared during its' first move. My tank is a Red Sea 350 so 73 gallons and has been running for about seven years. Has anyone else had an anemone just disappear? There are some places behind the rock that I can't see. I had a fish store check my water and all was well. Thanks to anyone who has experienced this or has a solution.
