I was wondering if you guys could tell me if my boa's enclosure looks good? I was having problems with the humidity but after I put a towel on half of the screen top it seems to be helping to keep its around 60-70. The cool side is like 70 and the middle is like 75ish and the warm side is like 80. but depending on if the substrate it moved (so part of the glass is exposed) its like 90 next to the water bowl. (upper left hand corner). It is a 20 gallon long tank. I wanted to put a branch in there for him but I haven't found any good ones at the pet stores. Thanks in advance
