Carpet anemones are beautiful and vibrant, but they are also very deadly. The anemones can get huge, like well over a foot across, and they can pack a nasty sting that can debilitate a fish in a matter of moments. Because of this, the carpet anemones are notorious for eating beloved fish and great care should be taken when adding one to a reef aquarium. It would also seem that fish with a voracious appetite fall victim to these anemones the most. As food trickles into the aquarium and lands on the anemone, brave and hungry fish take a chance to steal some of the food away from the anemone. Sometimes this ends in a small sting, but it can also end with the anemone getting a far larger meal.
