Yeah exo terra uvb 100 what about now?Unfortunately, I don't see a linear UV lamp; T5 are recommended, but you can get away with a t8. There look to be a few other things that could be addressed by the help form, but the light alone may lead to the start of MBD. I assume you have a compact bulb, which are sold without adaquate disclaimers; mainly that they're pretty much useless if the animal isn't within 3 inches or so for the whole day. You guy's forearms look to have a bit of a bend; compare them to the photos of my dude I attached (he's a bit chubby, but you can see the straight line from elbow to ankle). Luckily, MBD can be halted and the animal live a healthy life if caught and corrected earlt
