I guess I must have ticked of my maroon clown pair, because the female just put a extra 4 inches of sand on my LTA! I am more used to them sand fanning than the opposite. I assume the anemone will unbury itself- I guess if it hasn`t by morning I will unbury it. I Have had the LTA for longer than I can remember, so I think i am going to put a 4 inch piece of 4in pvc pipe around it to keep the fanning down. Anyone else do the collar for sand retention?
