I've been intrigued by those LED fixtures with the "programs" like lightning storm and cloudy day, but I dunno...seems like it would stress the fish out. Plus I'd imagine it's annoying in your living room to have that light show going on in the background/corner of your eye.
Definitely a neat concept, though! And very nice to be able to customize the color of the light to what best displays your fish. I was considering one of these Current Satellite fixtures when I was LED shopping, but I had the bright idea that I wanted to grow plants, so I went with a really powerful Beamswork light without all the fancy lighting colors or programs...just 6500k. I kind of wish I had the options & programs now, but oh well. The decision was made and I'll live with it.
