lol yea, i always laugh at the graphics on the boxes, they had like 30 neon tetras in the 8 gallon cube. i've already talked with a reef shop owner and i'd probably get a clown or two and a goby or blenny. maybe a seahorse after the thing gets established, the shop just got some in when i was there. coral is definately going in to it, but whats the pc unit you mentioned? but there are no mechanical differences to either Bio Cube or Nano Cube? like same setup basically?
