As for the bright light injuring the fish, I don't know about optical injury but it might certainly sting. After all they are at depth and their eyes are dialated for night vision at that time. Fish eyes dialate right? So I would at least be like someone bounding into your room in the middle of the night and turning a big light on. I hate it when that happens. Does a HID have wavelengths that can cause injury like a lot of UV? Since fish do not watch the sun at the surface with dialted eyes I discount the sun in the eyes analogy.
Illuminating them makes them visble to predators and getting them on the move will make them vulnerable as well so disruptive divers are not doing the resting fish any favors.
I find night diving to be a very intimate "small space" experience so a modest light serves me well (PT E-LED). I often run it on low power.

It's certainly a bright little bugger.
