When I 1st heard about these beautiful anemones, it was because one had just eaten someone's beautiful, expensive wrasse. Since then, I've been doing tons of research on them, as I was also concerned about what it mght eat in my tank. Even more concern is what nearby corals it will kill. Mine is kept 1' away from touching any other corals. It is fed meaty foods every other day, as it does not use light for food. As you may have seen in my thread, it is quite adept at catching fish. I put 2 doz guppies in my tank for a frogfish & the anemone caught every single one!
