Ight so the other day I picked up some aspen, a rat water bottle and some rat food... I was only planning on using my 20L for a holding tank for live feeders since I only have a couple feeding on live rats. I think I want to pick up a male and female rat and try breeding my own rats... Down the road when I have more room I plan on breeding all my feeders for my snakes to cut out costs... Anyways enough background ... to the question...

Am I good with just picking up a male and female... putting em in the 20l set up with food and water and letting them do their thing? Ive heard stories of one eating the other(dunno if that was rats, mice, hamsters...etc) Do I need a separate tub for the male or female for whatever reason? Potentially how many rats could I keep in the 20L? I dont plan on doing this today or anything Im just trying to see what else I need to do research/set up wise before I start. Thanks in advance.
