Before getting an anemone there are a few things to have in place if you have corals because they are known to move to where they are happy. One is to try and find one that is from captive stock. There are people that actually do divide them. I got one that the care card that came with it had on the bottom "sliced and diced at home". I say this because they are much more likely to stay put from what I have learned from others. You will need a good light. Mine is under 150w mh
and I feed it every 3 days food about the size of a pea. The day after I feed it I do a small water change. Mine has grown so much I have had to move my corals around to make room for it. They need a very stable tank I use an ATO to keep the sg
stable and do several small water changes instead of one.
