I know lots of people...
They're not all hormoned, but lots are. If it's colored up and less than 2" - you can be pretty sure it's juiced. There was a 1.5" z-rock at the lfs a couple weeks ago that looked better than my 5"er. That thing was so blue it was black, with a gold blaze...
And yeah, my fish looks female-ish now, but was BRIGHT red at the store. In my limited experience, female OB's have little color and are mostly a tan fish with black spots. My female is still maroon all over, though this will eventually fade, I imagine.
