Its a 55, I know thats large especially for a baby, but as I stated... It is free. I am also putting lots of things in the tank so he feels safe, multiple hides, I know its not necessary but possibly a climbing stick, because I have read they arent natural tree climbers but they will climb, and it will take up space to make him feel more comfortable . Would you recommend any plants? My humidity is around 65 but thats also right next to the water dish so that is slightly skewed, but in the middle and on the basking side its closer to 55ish. Today I am going to home depot to get some Shelf liner to black it out, I was most likely going to go with a similar set up to the tank in this thread, http://ball-pythons.net/forums/showt...p-w-pics-*DUW* , And once I get my other uth, t-stat, and a few other things im getting today I will post pictures of his set up.
