Ok so I'm about to adopt two adult normals. The guy who currently has them has them both in the same tank so I'm gonna get them and possibly breed? Anyways my question is what do I need to breed rats? I plan on euthanizing them for f/t @ various stages because I already have a baby normal? How hard is it? What kind of setup do I need? I don't want to breed rats but there's nowhere besides petsmart to buy them so....? Sorry the posts so long
