I have a 12x6x6 nano aquarium. I have some added a Hydor UG heater and a Deep Blue HOB filter. The substrate is a flourish substrate. I also seeded the HOB filter with some ceramic rings from my other tank. I intend on some Newbie shrimp and some moss. I have a 12" 33 LED fixture on its way as well as a pretty cool piece of driftwood. Any suggestions for a newb???
