OK i propably go with 32 qt RBI Rack.
Quote from RBI Rack Faq:
"How Big of a snake can I get into one of these? What else will these house?
We routinely keep baby balls, boas and colubrids in the shoebox rack. Baby balls are comfortable up to about 300 grams, baby boas up to about 16"-18", and colubrids up to about 20"-24". Also an ideal box size for growing individual terrestrial geckos.
The 15 Qt.MCB-S tub works well as a "grow out" tub for baby Balls (500+ grams), Boas, Colubrids or Geckos. Some smaller species may do fine in this tub for life.
The Sweater box rack (MCB-L tub) will house balls up to about 2000g, boas to about 36" and most adult kings and corns. These boxes have a little more floor space than the old Rubbermaid sweaterboxes us oldtimers used to use. These boxes also work well for small colonies of terrestrial geckos such as Leopard geckos or Fat Tail geckos."
Ok i know 2000g Female Ball in 32 qt tub is too much but I plan expend to 41 in the future... and honestly i love get some eggs but I don't gonna breed BP for money but for my own satisfaction. I dont need get 8-14 from super large females.. If i get 4-5 from 1300-1500g female i gonna be more that happy :)
Anyway Thanks for Your help Guys and Girl :)
