So my nepthea tree is laying down and not looking good but i think its doing what i read from tidal gardens website " Nephthea will periodically retract its polyps and form a waxy film. This shrunken state may last a couple weeks before the film is shed and the polyps reextend. We believe this shedding is a healthy process that Nephthea employ to prevent nuisance algae from growing on it. This process can be aided by greater circulation around the coral". Do think this is what its doing?
