I have two 30 gallon aquariums I am going to use for a mice breeding colony. The dimensions are @36"x12". How many breeding mice can I expect to keep in a cage of this size. Currently I have set up just one cage with 1 male and five females. Is that to many or do I have room for more females. I dont want to overcrowd but I also want to maximize production with my cages.

Thanks
