Thanks! I find that the fish in my 20 long prefer and look best in dim/isolated lighting like the 10 gallon above, which is lit by one small clip on lamp, but the plants don't.Very good, sir! Nothing better than feeling the liberty to do what you feel like rather than what is "required" by the norm. Leaves a bit of interest when guessing what is in the shadows. Maybe a bunch of small fish enjoying the hiding and safety ? Or is it a big guy lurking and waiting for the small ones to make a mistake? A few mysteries can be good for us!
