does anyone know anything about breeding rats??? i want to start a rat colony in the 55 gal tank when we move roo to as better sized 30 or 40 tank. i know nothing about breeding them. i would figure just let them do their thing, and some day maybe they would pop out tons of babies. i know i would have to seperate the babies from the adult males as not to get killed, but other then that i thought rats and stuff bred really fast???? any advice or help????
