I have T5 ATI PM lighting. Not sure if it's a coincendence, but as soon as my main light goes off and only the dusk/dawn light stays on, the male flame wrasse flashes much more frequently. My dusk/dawn light combination is fiji purple with an ATI blue plus. Maybe the cooler lighting puts the male flame wrasse in the mood. Sort of like dimming the light in your bedroom. :inlove:
