Firstly ... sorry for starting another thread with questions that have been asked to death! BUT... the search function doesn't allow "50L" or "RUB" to be searched so my search sort of failed.
Basically its my birthday in a couple of weeks, i know i'll get $200 dollars from my aunt in USA (about £120 at the mo) and maybe a few other bits and pieces from relatives, so i thought a good plan would be to build myself a rack and buy rubs with this money

(i'm thinking i'll have about £150 overall to spend).
so the questions...
In the rack i will want to have space for...
2 corns when adult (08's at the moment)
2 nelsons milks (already in 50L rubs)
2 female Leos (living together but with enough room for male to join them during breeding)
1 male Leo (by himself)
1. are 50L rubs ok for adult corns?
2. what size RUBs will the Leo's need?
would 50L rubs be ok for all of them?
also whats the best material to make a rack out of?
thanks,
Elsa
