Help with male and female leopard geckos fighting

[Nibled]

im not sure if anyone can help on this site butI bought two leopard geckos two days ago and they lived in the same vivarium when i got them but today they started attacking each other. Im not sure if its to do with breeding but im slightly concerned and would like an answer to this problem ASAP.

Are you certain of the sexes? It sounds as if you have two males to me.

I agree with Chip. For sure you have two males. They have to be separated as soon as possible.
