My second anemone, the child, emerged from hiding yesterday evening and started crawling up the back glass. It got dangerously close to my overflow so I decided a relocation was necessary. I removed him from the glass quite easily and placed it in the crevice between two rocks. It has moved about 6 inches from that spot in the last 24 hours. The nightmare scenario is this guy getting sucked up in a power head and nuking the tank.
