I really agreen with you there about water fluctuations coraline.... I have been doing only nano tanks 30 gallons or lees since I got into the hobby about 2 years ago. My little watchman is pretty timid as well but is getting a bit bolder as time goes by. Eventually I would like to get a shrimp for him but I am going to give the tank a little bit more time to settle in.

I was able to get some pics of the tank so far.

The next thing I want to add is an enclosure for the top to make it a bit more pleasing to the eye as its in a trafficed area of the apartment.

Here is the HOB filter and some of the mods I did to it
