Manny appreciates the love, thanks! Ok, I thought someone might be interested to see my tank under the new 'moonlight'. I got a 3/4 watt blue LED 'moonlight' for the tank and it works pretty well. It's on a timer set to come on for a few hours starting just before the main lights go off. The nocturnal loaches come out as if it were night and the betta seems not to be bothered by it. It's at 470nm so it has a similar effect as a blacklight. This is the best shot I could get - it's a bit brighter in person. You can see the silhouette of Manny in the foreground.
