There are many reasons why "no" on the carpet anenome. There are also many reasons why to get one. Anenomes require prestine water condition, strong lighting needs and without going into the whole history, need to be added into a well established tank. The carpet anenome grows very large, can move large live rocks when on the move and kill corals in its path. They need to be fed seperately and if not fed enough might enjoy one of your fish. On the positive note, I love mine. He is over 1 foot fully extended, has stayed in the same spot for about 10 months ( before that he moved some large live base rock that was huge ! ) and provides a great home for my clowns. First look at the size of your tank, your lights and stock. I wouldn't put one in a tank less than 125 gallons but thats just me.
