I watched a lot of videos on YouTube and read a lot about peoples racks so I decided to build one and I did a 4 tub adult rack and I also read a lot about two hides witch my snakes do have now there still in seperate enclosures not in rack(temps and everything fine) but all these racks I see in videos have one hide is it because they feel more safe in a rack only one hide is neccessary? I'm gonna stay with two for now they def utilize them jw
