This is my first anemone. Recently bought a bulb tip anemone from my lfs. The anemone looked great in the store. I brought it home and transfered into my DT on the same rock that it was on in the store. It was doing great in the tank for a few days. Recently (last 2-3 days) it has been shrinking into its hole in the rock so you barely see it at night and being very small during the day with lights on. Yesterday I tried to spot feed to see if that was an issue. It grabbed a hold of a couple pieces of mysis shrimp, but did not eat right away. A minute later my cleaner shrimp jumped on it took all its shrimp (is this normal). Please help with any comments or suggestions. My tank is a 65 gallon reef 36"x18x24. I have 5 chromis and a pair of clowns and a clean up crew . I feed the tank once a day with mysis or cyclopeze. I have had the tank running for 7 months.
