Mine was lack of powerful enough lighting. It is actually caused by the symbiotic zooxanthelle dying. Are you feeding them directly? mysis shrimp or brine?? Soemthing? What type of lighting fo you have?? What are your water parameters???

If you have t-5's or metal halides, it may be time to change your bulbs. If not could be fluctuating parameters.

I agree, it sounds to me like your lighting isn't strong enough. Do you feed them anything?
