Thanks!
The last one is an Orange Crush Acan from AtlantisAquarium.net. The subjects are all in the first 6" of my tank. Because of the extension tube I didn't get a read on my F-Stop in the XIF. I'm sure I could figure out what it used, but I have no idea off the top of my head.
The tank was on actinics only at the time (2x440) of the shoot.
The last two pictures were taken under
NightSea filtration and flashlight lighting. That's some amazing stuff right there. Well worth the money to pick it up if you have a good DSLR setup.
The only post processing was resizing and borders.
