Hi ummm I didn't say anything about a 10 gallon tank set up.

I have them in a rat rack with the cement tubs.
I keep two per tub.

Fixing to try to transfer around soon since babies are growing and getting mobile.

I was thinking about putting the birthing moms in a rack like others have made that is smaller then the tubs I have now so they can be alone . I see that a lot of people do this.

I do not want to use any tanks as they are way to heavy for me to deal with.
I clean the tubs out at least once a week and I can't be lugging the heavy tank in and out that much.

I think there is plenty of room in the tubs I have esp since I see on you tube where they are wall to wall rats in these things. I would NEVER put that many in one tub.
I think 2 can live comfortably in them. Even with babies. Although now that the babies are moving around a lot more I will proably be re arranging some of them so that there enough room for eveyone til they wean.

I have a really large Martins cage that I will put the babies in for a while til we co2 them.

Thanks
