Hey Bryan,
The blue lights certainly are quite visible to the marine critters, as that wavelength travels best underwater. On the contrary, cephalopods are much more relaxed if you use a red focus light. Perhaps a good option for your fluo dives, at least for stills (focus with red, and strobe-light with blue).
Things will get easier with the rebreathers. I am glad my talk could help you make a choice, you’ll love your Horizons. Being in Singapore I presume you’ll be speaking with John Chee (Horizon instructor & instructor trainer), say hi for me!
No issue at all to paste external links if you’re sharing a raw file. If sharing a jpeg, I recommend attaching them to the post (file needs to be max 1 MB, resizing to 800px should do). They would be easiest for forums users to see this way.
