Hi,

It may suffice if they get along, but watch them closely as a dominant animal may stress other, even if both are females; be sure there are plenty of basking sites close to the UVB bulb (6-12 inches), lots of sight barriers (plants) and so on; pl see this article on their care (links to part 2 is there as well) and let me know if you need any info, enjoy, best, Frank
