The interesting part is the T5 tube it sits directly under is a blue actinic I use to help balance out the 5500K LED pendants that are a little too yellow for me. The tank is an angelfish final pairing off tank, so these are large, brightly colored fish that really show well under the lighting combination when I'm home. The blue spectrum I suspect is what keeps growth in check, but interestingly intensified the pink.
I found one that's even more red than the one slightly left of center in the photo. I mean it's cardinal red. I still haven't put this one in a Rip yet. I'll see what the variety is when I get home. Can't remember off the top of my head.
