I added a beautiful, rather large & very healthy-looking long tenacle anemone to my 2-yr-old tank a week ago today. I have a pair of clowfish who hosted my brain coral to death, so I thought it was time to get them their own. The anemone was thriving up until about about 3 days ago. He moved himself a few inches from where he was. Then he moved again. Then his foot became unseated & he shriveled & swelled a few times. Since then he hasn't seemed to find a spot he's content to put his foot down in. He's still sticky and he ate a piece of shrimp this morning. The LFS told me somthing was probably irritating his foot. There has been a lobster hanging around very near him. I examined (on their advice) his foot for signs of tears. Fortunately I found none. Then I moved him to the other side of the tank (the lobster-less side). He's looking shriveled up like a freshly-moved anemone looks. Anyone have any advice or experience with this matter? Is there anything else I should or shouldn't do? Please help!!!!
