I like it, keep it small and simple!!! though I'd raise the light up so its not so intense on the shrimp since you have just moss.
The light was only on for photos. I don't keep a light on this tank
It sits about 4 feet from a window so window light and room light is what it gets. Every now and again I put the light on so I can check everybody out a little better but other than that, just natural light on this tank
