My cousins 120 gallon reef tank has one tube anemone, and lots of live rock and and two sunflower corals on each side, the tube anemone has got green and black spots EVERYWHERE!!! Even on the tube!!!
       It houses one male mandarin fish, and one bicolor angel, Nitrite is 0 Ammonia is 0 and the SG is between 1.023 and 1.025.
What could be wrong? Sorry, those were the only radings I could get hold of. The filter is a aqua lab, something, something. Two heaters in the 30 gallon sump. Tem is 79F-80F.
One protein skimmer on the side of tank, next to the sun corals.
Please help!!
