Can female and female Leopard Geckos live together?

Yes, but two males is a bad idea. and unless you want baby gecko's, no male or female. However, make sure they get along. i had 2 females and they fought alot. one had to be put down as she stopped eating, which the vet blamed on the other one stopping it. Any danger with gecko's is cage mates accidentally standing on eachothers tails. be aware of thses facts before getting another gecko.
