I have a 7 month old Kinyongia vosseleri. He is in a meshed repti cage that measures about 24x25x48. He has a large bushy umbrella tree inside with vines etc. Right now he just has a reptisun 5.0 uvb bulb. Is this enough lighting? He has been doing fine so far with a good appetite and activity level etc. I live in Canada so it is going to get a little cooler soon.
