1) how did you get the fish to flare all of their fins in your hand? Normally I get really clamped looking photos of darters in hand. Are these live fish, or fixed?
Anchient Chineese Secret!!!
The secret is patience. You have to sit there, continually dipping in and out of the water. They'll splay when you put them under and you're trying to get them tired enough to just let their fins stick the contours of your hand. Yes, you are essentially "Air Boarding" the fish
But the fish is still alive and I've brought home specimens that I've done this with, and have found no ill effects. It's not as uninvasive as Uland's process (which really is the most efficient and least harrasing for the fish), but I can get a good shot right then without having anything else but my camera.
I also make sure the fish is fully resuscitated before letting go (they'll dart off when they're ready). This worked out really well in this case, as Jeff had his underwater camera and made "habitat shots" in the Fish Dome . This is another old trick of mine... Wear out the fish and then take pictures in habitat while you make sure it's good to go again. We took that to a different level this trip... In fact, that's what Jeffro was doing in that pathetic picture of us in the rain.
2) Are these ty[pical nothototus, meaning they were lighter in color underwater and got darker as a stress response? Or was the substrate in this area really dark?
Nope, light-brown colored polished sandstone like you see all over the place in the central highlands. They look less colorful snorkelling because of sediment eating up light. You wouldn't believe how much dissolved sediment is in water, even fairly clear water. There are only a handful of streams that I can think of that will have the clarity where you wouldn't want to adjust the contrast in Photoshop after taking the picture. And most of those are bluewater springs in Florida.
The specimens will diminish in color as well as you "Air Board" them. Stress from being with all those other species in a container may have them all fired up (I've seen dominant male Nothos chasing each other around a bucket before lol) but they weaken in color as the process goes on, and they start to stop fighting. Sounds awful, but I don't see how this is any different than fishin' for sportfish.
The trick (again) is to put them in a LIGHT colored bucket with GRAVEL in the bottom. We held all these fish for over an hour. We used a Home Depot orange bucket this time, basically because it was on top in the bucket pile when we started, and then it was the one with the gravel in it... But if it were any warmer or brighter, I would have used a white bucket and got the same result.
Just say NO to black buckets!!!
And as far as video is concerned, bring on the Hydrophlox!
Will have it online this weekend!
