I have a 15gal glass tank and he has a warm hide and a cool hide -- the cool hide is one of those green moss ball spheres but he mostly stays in the hot hide during the day and just climbs on top of the cool hide at night. I mist it three times a day pretty much in the morning, afternoon and night. I use cocoblox as a substrate and had initially put around 3 inches but thought that may be a bit too much for a baby? But the humidity was doing better when I had the three inches (now I only have about half an inch. I also had to put a ceramic heat lamp overhead to maintain the correct ambient temp which is also contributing to the dehumidification of his enclosure. I tried putting foil over 2/3rds of the mesh top but it hasn't done much. I can't really get a good view of him since I don't wanna spook him but I think it is mostly on his tail and mid section, not on his head though.
