What is this and how should it look? Appears to be LPS but idk. It never opened it was in moderate to low flow in at the bottom. Moved it to the top in high flow and it started bleaching. Moved it down to middle and bleaching seems to subside. Tried feeding no change. 2 acan frags from the same order receded while Duncan has sprouted 3 new heads and frogspawn, Zoas and monti cap frags are doing well. What can info to save this thing?
