Hi I am the mamaj. I am adopting a 4 year old dragon and will be bringing him home in about 2 weeks. The lady I am adopting from has a 40 gallon breeder with mesh lid I will be getting. I wanted to have my other supplies ready for when he comes home but every article, video and post I have read the lighting recommendations are a bit overwhelming. Can you tell me if it would be better to buy a Reptisun 10.0 T8 and a under the cabinet florescent fixture from Walmart and mount inside tank or a T5 bulb and fixture that would sit on top of tank. Which fixture would have the greatest health benefits for my dragon? Thanks for your help! This is my first time owning a dragon and I want to start out right. I can't wait to bring him home.
