first, your current tanks: list still cycling? your anemone is not gonna survive if your cycling in the same tank. you need a well est. tank of at least 6 mo. or longer. they do love light and current and they will move to where ever they feel to be at that particular moment. overflows, powerheads, your favorite coral. just where ever. as far as light, i recommend the daylight hours where you live. not dawn till dusk but the full day hours. appx. 10, any more is your call. some go as much as 14, IMO thats to much. good luck & REEF-ON!!!
