I have a 40 gallon tank which is a month old with a large filter, Biowheel protein skimmer and a 500gpm water pump for current, temp is 78, Nitrate 0, nitrite 0, alkalinity 270, ph 8.2. Two lights don't remember watt but its a coral sun, and reef sun. I have 1 blenny, 3 hermits, a cleaner shrimp and a damsel. Being new to the hobby was miss educated at a local pet store and the owner told me it was relocating and the color was normal for the type. But later researched and found it is supposed to be tan.
