Mollie suspect the same thing... That it was a "greenhead", but couldn't rule out some influence from lutipinis (as a hybrid).
I don't think it's light. If it had been this blue under the limitation of colors from aquarium lights, I'd say it was light. But the flash corrects the absence of any wavelength, and actually made it less "purple" (which is how it showed up in the video and in person). That, and I can hardly say there's any absences in the red spectra
