I've been keeping fish for almost 13 years and I feel that I am ready to move on to a reef tank. I would like to start out with a 5 gallon reef tank. I know this is daring but I want to be practical before I spend thousands of dollars on a larger system. I don't plan on adding fish to the tank. Can you give me some suggestions to invertebrates and equipment that you've found useful? If you have a reef tank less than 10 gallons, would you please share a picture along with the size,lighting, filtration,additional equipment, and livestock?
