Small animals in big enclosures

One of the key parts of my animal collection planning is the size of tank I can provide and how much space this will give the animals. I always like to go above and beyond with extremely large tanks and a good example of this is my 90x90x45cm exo terra terrarium that houses a breeding pair of Phelsuma klemmeri. It has an Arcadia 6% UV bulb paired with a jungle dawn LED and a 100 watt flood spot heat bulb. I hope to get a UV solarmeter soon so that I can provide an even more accurate UV and a better lighting system in general.
