Thanks, yeah... I think he is pretty big... Larger than I expected. He has already eaten some. I took the food out of his cage yesterday and will feed him again tomorrow... I plan on feeding 2-3 x a week and leaving the food in overnight then removing the next day.
Humidity has been about 70-80%. I got the raised tile idea from someone on the BTS FB group. They said to use irrigation system pvc tubing (about 6-8" tall) and gorilla glue it to a tile, thus giving it "legs", then use a narrower tile as a ramp of sorts. I think it would be pretty stable, although I'm not sure about how to secure the "ramp".
