The comment above basically covered their care. They require brighter lights than a lot of corals do, and they move around a lot. Many people become frustrated with anemones because you will put it in a desired spot, and the next morning you will find it on the complete opposite side if the tank. Sometimes if you point your powerhead pump at the spot that you want to place your anemone, you will have a better chance of it staying there, but most of the time you will not have control of where it goes. Just make sure it doesn't get anywhere near the actual equipment because I have had anemones travel into my pumps and filters and get chopped up into dust from the impellers, and then get sprayed all over the tank. Also, make sure they don't get near your corals, because they will definitely sting them.
