Hi Jo, I agree with Jonathan Hermani Boettgeri, if you want to get another, I would recommend you get the same species. At this age there is no garrantee what sex they will turn out to be, and if you end up with one male and one female you will have to separate them , as the male will become agresive to the female and pester her all the time , she will become stressed and this could make her ill. Two males don't normally get on well either, unless you can give them a lot of space in the garden, so they can keep their distance from each other, two females usually get along ok.
