Maybe. Mine always seemed to vanish behind the live rock in the tank. But one of my tomato clowns actually took to it, but i think the clown was to big because it seemed to wallow sorta hard in the anemone. After 2 vanished without a trace I sorta ceased to buy anymore because now i don't really condone the collection of wild anemones, because of the captive mortality rates, and thier very low reproductive rates, and the loss of a clownfish habitat every time one is harvested, buy hey it's justmy opinion everyones welcome to thiers!
