This is my 3g Pico tank. I'm housing several different types of zoas, a couple of blastos, and 2 clownfish. The clowns in this tank are not mine. I'm holding them for a friend for a few weeks while they install a new tank.
I'm run a HOB filter, no skimmer, and use a Nova Extreme T5 fixture on top. I have a small Rio powerhead as well.
