Well about 4 months ago I bought a pair of skunk clownfish with a GBTA and it looked really green when we bought it and now it's like a brown color. I feed it once a week with mysis shrimp and the light I have are 4 bulb T5 and the tank is a 92 gallon. All if my water prameters are perfect and it eats well and everything but it's just not green. Is there anyway I could make it "green" agin because that would be very nice.
