Rock Beauty Parasites

[thereefmaniac]

I have never see this problem. During the daylight hours the fish is fine. In the morning before daybreak he is in a corner discolored and breathing rapidly. I come home from work and he is back to normal, eating well and all. Every morning when I wake up it starts all over again. I have a 115 gallon tank with a 25w UV sterilizer, skimmer,chiller{I live in s Florida} The only other life in the tank is a maroon clown with an anenome. They are unafected. Any Ideas?? I have done water changes, with no help. My water readings are perfect. I even used a non copper based Parasite killer medication as my Fish store recomended to take care of the problem. Whats next???

some fish a night will fade in color and usually sit in one spot. my damsel is very ugly in the mornings. but after the light has been on for a short time he returns to normal.

Does the lights to your tank suddenly go on when it is still dark in the room? This will really stress out most fish, if so.
