I have three anemones. A green carpet, a rose bubble, and a purple lta. The carpet is huge and seems to enjoy the heavy water flow in my 180gal aquarium. The rose hosts 2 maroons, with the female being very agressive. However it is planted. The lta however moved around and was getting stressed so...
I moved it to my refugium and I disconnected the pump and put in a small powerhead. I left it for a few hours and it attached itself to a rock in the refugium and has been inflating. It's obvious the heavy water flow was the problem. I'm going to need to attach a smaller pump to the fuge so the anemone stays happy. Even directing powerheads away from it initially didn't help. It needed the more tranquil environment. Hope that helps.
