Hmmm the only issue I have with mine is it likes the dark. It keeps crawling between the cap pedals and killing them. Maybe it is getting too much light? By the way for those who don't know, sexy shrimp are symbiotic with them and they make a cool combo. This has been the only time I can see them in my tank. They hang right on the Maxi Mini and dance away all day. The anemone protects them so even my hawk fish avoids them.
