a specific echino in my tank seems to be loosing alot of color and browning/bleaching almost. I recently ugraded my lights to a T5 on my new set up and i think the little guy was getting to much light? it was on the sandbed (however directly under daylight bulbs) i moved it this morning to a shady cave hoping it will regain most of its color. The other corals seem to be doing fine its just this specific one. I acclimated them to the light starting with 4hours a day and working up...im up to about around 6 hrs a day. Any thoughts on my echino?
