Nice, i had a big setup like that but as wierd as it sounds, to me its easier for me to clean a bunch of small tanks than one big one.

I stopped keeping track of the babies ages, i just kill them when they are big enough.

I have 4 mommas with babies and one who is pregnant.

Like ive said before, im getting out of breeding most likely, im just waiting for these babies to get a little fatter, them im just going to keep two mice (sisters) and borrow my friends male every so often and get them pregnant.
