here in a few weeks going to have to start breeding rats (never breed rats before so got no clue) what size tub or tanks should i use can at first use tanks when all said and done want to have a few racks of them for breeding any ideas on what size totes or tubs to use and how many per tub(i have read rats need more space then mice) don't really care if need to go with a huge tube to have more then 2 females per male.

any and all advice will be thanked
