Thanks for replys guys/gals, I wanted to get the skinny on mercury vapor because i heatrd they were good. Im finding im having less time to sun, my critters so I considered it. Im tossing up between that and building o/d enclosures. I think ill wait till spring though, get a bit more size to them. I though about a walk in enclosure with a pond inside for the turtles, and keeping, the blueis and beardies in there too, it would be a big one, im a bit concerned with the blueies drowning though. how does anyone else do that, really gently sloping pond sides and lots of logs as ramps out?
