My first tank is a 55 gal with 2 clownfish, 3 damsels, 1 coral beauty, a couple shrimp snails and hermits, about 30 pounds of live rock. I have more curing in my next tank (30 long) right now to get me over the 50 pound mark. I definitely want more real estate for corals in the future. Right now it is running a bio wheel 350 filter, Hang on back skimmer, and uv sterilizer. I am building matching stands for this and the 30 long soon and will be adding a 20 gallon sump to the 55 (any recommendations on setting up the sump)
