no problem... well on lighting, I have some heat bulbs on my tank.... On my species of crocodilan they are not out in the sun to much and therefore don't really need a uvb bulb but scientists, zoologists, etc. don't even no if they need one or not... but I got one anyway (just in case)... I would recomend a heat bulb and a uvb for your species of caiman... because specs. are always out in the sun... by the way where are you looking to get your caiman?
thanks for the comments...
