Have had this millepora colony for a few months now. When I bought it it was pink with light blue tips (hadn't been in the shop very long) placed it half way down the rock work and lost the colour in tips and slowly turned to a purple / brown colour but had great PE. Figured I'd try it higher in the tank (also in stronger flow) and although colour is now a lot better , I've got a lot less PE. Worst of all is it is now STNing from the base up ? Or is it where the upper branches are blocking light from the base ? If STN would you recommend fragging to save the colony ? Or is there another way to reverse the damage ? All other acros doing fine.
