I've lurked for awhile, only just got an ID, and only started a couple of threads. This one is important to me. I'm adding a male pastel to go with my December acquisition, a female spider. I've never used tubs before. My first ball is a normal, pet store purchase who feeds like Jaws. He is housed in a 40g aqua. Never a bad shed. It's easy to admit that I got lucky with him. However, as space becomes limited, I'm looking to go to tubs.

My questions:
1. Is there a general size chart for tubs? IE if snake a is Xin and Yg he goes into Zqt tub.
2. What is the best method of puncturing the tub?
3. When will the addiction end?
