BigBalls: We are not actually Hating on glass tanks, as I personally prefer them. The OP lives in a loft apt. on the 6th floor, so hauling glass tanks around really isn't a viable option for him.

Loft Lizard: Those posts of yours are Terrif!! I also live in an apartment, and recently moved down from the 3rd floor with my snakes (not fun) so I can sort of relate to the OPs situation. But you are Da Man for this thread!

Derteufel: I also think a shelf in a closet would work well, as long as you remembered to have air circulating in there Sounds like you're really starting to get down to it.
Also, I should have realized from your name that you would be German. Cool. I'm 1/2 German, but have sadly forgotten most of the language.
Good tubs to use for a baby would be a 12 quart Sterilite or Rubbermaid, easily found at places like WalMart and Lowes. I'll let the others chime in with breeder recommendations.
