so i been thinking about making a vivarium, i have an 55 gallon hexigon tank i think it would do well it, but you can only get to it from the top, and on youtube it looks everyone has doors on the front of there tanks,. is this just to make it easyer to get in or is there another reason?
It's just easier with the doors. You can definitely build it from the top. I'm currently building a 37 gallon tank for geosesarma crabs and I'm building only form the top. I'd imagine from the front would be a lot easier, but it's definitely doable.
