Carpet Anemone question

[Myanth]

I have a heteractis magnifica with two powerheads constantly whipping the tentacles around. It lives about three inches below the surface under a Giessman 250W MH. It stays put as long as I remember to feed it. I give it a couple of krill every few days and it stays happy. It's about ten inches across right now with three false percs living in it and spawning right below it. It has taken a couple of trips over to the drain and once all the way down it into the sump, but each time I attribute it to lack of feedings. The clowns seem to corral it into place since they started spawning as well, actually biting the tentacles as they reach for other rocks.

Just info but I hope it helps.
