Nice pic!
The Yellow tang's pose is actually how my username came to be. Kind of an inside joke between my dad and I, but when we had our first tank when I was younger, I got a kick out of when the tang would shoot his fins up like that. Well, my dad had built a housing to hold the MH ballasts, and it had switches on the front. There was an extra switch, so he jokingly labeled that one "Fins Up/Fins Down". So that is how I came to be FinsUp!
That switch never did work right though...
