So to capture the fluorescence in the coral you need blue gel filter on a flash or a source of light ie blue led brighter the better. Then a yellow filter on the lens to really see it. The hard part is focus if your light source isn't bright enough really hard to focus in. Glad you like the photos and Couchrugby Thanks for setting me up with the proper equipment.

Marlin65 sorry my other camera is not here at the moment. I'll try to describe what my set up is. Shelps, No I wish. The night gear is what I am trying to simulate. You can do this a few different ways for my light source I'm using a speedlite 580EXll with a gel filter (blue) over the flash. I also use a strip of 10 blue LED's on a oscillating arm, this is so I can focus. I think night gear is the way to go because it is way brighter maybe to bright that is why I don't have one yet. You can even put a blue filter on a flashlight.So far I like my flash hand held the best. For the camera lens a yellow screw in filter (had to order). Then the custom photo tube built to fit my camera and lens. If any of you guy try this keep in mind it can be very difficult to hold a camera over a tank try to focus and hold a light source without dunking something in the water. I like to take multiple pic of different things so I don't like a stationary light source. I also built a rail and handle to hold flash and multiple other light sources. I'm still experimenting so I would love to here different suggestions or what works for you if you try this.

I think to get the true fluorescence you need to use an actual UV light source. All that is suppose to show up is the corals natural florescence, obviously if the rock is lighting up it's not quite the real thing. You can order fairly powerful UV flashlights off line for a decent price. I've always wanted to get an actual night gear filter but never got around to it. I did some similar experimenting with similar stuff to yours a while back and the results sure are interesting. I'd really like to get into it a little more so maybe I'll see what I can do.
Great photos and thanks for the inspiration.
