Camera is a Sony Cybershot DSC-H2 6.0 megapixel w/ 12x zoom. Just used the default auto-adjust setting without flash. Took the pics at night with no other lights on, stood about 8 feet from the tank and used the zoom to get in close.
The tank is actually an upgrade from a 30 gallon I had for about a year and a half. It's been up since late september, had fish and coral in it starting in november. 70 gallons, no sump, just fluval 405 canister w/ prizim skimmer on the back. 2 sweeping powerheads (don't know the gph) as well as one stationary head at about 400 gph? Outer Orbit light with 2x96w dual-actinics and 1x150w metal halide.
