Thx! The next tank i am thinking about is the same one, Aqueon 15 column for my shrimp tank. I want to find a nice chunk of driftwood that is taller (like a stump) and then fill it in with moss and anubias, pressurized CO2 and a canister filter. I am planning a new stand to have both tanks on top, and the 5gal under for my plant tank (storage). I'm also working on an Opae Ula tank, something about 2.5 to 5gal.
