The water parameters are 0 ammonia, 0 nitrite, 10 nitrate (or less depending on water change date). The water is kept very clean with a wet/dry sump, a coralife super skimmer, and a fluval 405 canister filter. The substrate is 2" of aragonite sand and there are petrified coral base rock and synthetic corals in the tank for decoration/hiding spots. There is a Koralia Evolution 1400 for current across the tank.
Here are some pictures of the puffer so you can see what I am talking about with the color change. He can go from basically all black, or gray with spots and stripes, to olive green with spots and stripes, to almost camo colored with spots and stripes! Sorry the photos arent so good. Blackberry Bold isn't the best for this!
