Today met someone in the lfs, he has a six feet tank, inside the tank, two queen, one blue, two emperor, one blue ring, one king, two french angel, one rock beauty, one Koran and other angels I forgot and also many butterflyfishes, and many tang, four pbt, two bpt, AT, and many more Tangshan, yellow shoulder I think. Amazing and nice video, now buying another rock beauty. But he maintains a very strict routine, two water change per week with 40 liter per change. And have four skimmers running.
