Well It is time...I am going to change from my Big glass tanks to a rack. Currently I have a Ball and a 5 1/2 foor RTB. I wanted to make a rack that has enough space for maybe 4 BP tubs and maybe 2 Boa Bins. I am curious what the best size bins for keeping these two kinds of snakes are. I would love to see pics of anyones custom racks that you guys have built and use. I am going to making this myself and would appreciate any tips. Thanks in Advance.
