It depends on if you are going to have multiple enclosures. I started off with 1.2 so that I could house them together and then later down the road introduce another male in a separate enclosure. The 1.2 have me eggs sooner and more of them since they lay such small clutches. Pygmies are communal in that they can be housed together. However two males cannot be in the same enclosure. Those little guys become very territorial.
PM me on details about carpets if you wish.
