I have been having a problem with my zoas lately, mainly my green zoas. All other corals are fine in my tank except for this colony of green zoas. They seem to all be losing/ switching color and shrinking. i can now see the rock they are on. All other zoas colonies are ok, but whever green zoas are they are all having the same affect. i have possibly too much lighting 2x 175 watt MH and 2 96 watt actinics on a 55 gallon tank. the light sets about 6 inches above the water and goes for 8 hours on full a day. adequate flow is on them, and the mian colony sits on teh floor of the tank. all other corals are fine in my tank remember. any suggestions?
