Hey fellow boa-ers. I'm new to keeping snakes I adopted a rosy red that was really about 7 months old from a family who couldn't care for it. I've had Walter for a week and he's being kept in a 20 gallon terrarium with aspen bedding. I've been told that over head lighting isn't truly necessary so I have an under tank heater and a ceramic heat source from above to keep the temp in the tank warm enough. I have digital probes and a infra red temp gun the temp in the terrarium is 75 on the cool side, 82 on the warm side and the warm spot is 89. My concern is the humidity. I can't seem to get it below 50%. Is there any way to do this? There isn't any water in the enclosure as of now. He hardly ever hides and seems to enjoy just hanging out but I want to get the humidity down to a more reasonable level. Any information on absolutely anything would be helpful. Feel free to give me tips on everything concerning my new friend. Please help.
