Inow have a 29 gallon tank, with approx. 15 lbs of live rock. The big pieces of rock are still fairly new. I have one small piece that is pretty neat. It is a bunch of sea fans and polips. The fish that are in the tank are 1 Blue Damsel, I blue Fin Damsel, 1 Niger Trigger, 1 Maroon Clow, and 1 new Lawnmower Blennie. Also in the tank for inverts is a Coral Banded Shrimp and a Fancy Brittle Star. My bottom is medium grain sand. My filtration is 2 sit on top filters and a good power head for water movement. My lighting is a 10k buld and I am trying to get some night lights set up so I can enjoy a different side of my tank. Let me know what you think.
