Ok I will try, as I have kept nanos for quite a while. I think I have a picture of my 20H on my website. If not I will post an updated one in this post later. My nanos are always skimmerless and sumpless. I do run a Fluval 104 on the 20, because I need a place to keep the Chemipure I am fond of.
As far as lighting goes I have a Coralife 2X65W Aqualight containing a 10000K and an actinic bulb on the tank. The tank also has a two inch sandbed.
The inhabitants are a lot of zoanthids, one small Toadstool, some Yellow Polyps, Green Star Polyps, a few pices of Montipora digitata, a piece of Staghorn, and a pice of Hynophora. There is one Stenopus zanzibaricus that never comes out, and one Six line wrasse, and a Purple Firefish.
About all I do to the nanos is clean the film algae off the glass, and very occasionally change some of the water.
