It's all about floor space. Just consider the floor space, including the floor space in the hides. If they have enough room to comfortably chill in their hide, and enough space to stretch out, and/or slither to the other hide and relax, it should be good. As long as you're just temporarily keeping her in the enclosure until you get together a bigger one(maybe a sterilite...easy to come by, and inexpensive) it should be okay. I did the mistake of over crowding my 20 gal tank with plants. But I'm getting a baby, so I think she's got plenty of space for now. My hides are those simple clay plant bases(the short shallow ones) and they're perfect. Nice and tight for their security.
