I have been fascinated with this tank since I first saw it a few weeks ago. I cannot believe it is only 8 gallons. The corals are so close together. Do none of them bother any of the others? Is there rock in this tank? What kinds of lighting was/is in the tank? Just got a 16 inch biocube so that we will have another tank in case of an emergency and I would like to imitate your tank it is so gorgeous.
