How should I introduce 2 female leopard geckos?

[Tiphanie Oakerman]

So my dad is going to get me another female leopard gecko and I already own 1.when I got her at the pet store she lived with 2 others,but i am worried that since shes lived by herself that if I introduce another female with her she will bully her.My gecko is only 7 months old and when my dad gets me the 2nd 1 she will be 9 months old so i was also wondering if i should just have my dad get me a baby gecko or an adult.I already know about the whole seperate tank thing.my gecko is really nice so i dont think i would have to worry about aggresine unless i get an adult then im worried it would bully the gecko i have now.so if you have any tips please write back.

Firstly you need to quaranteen the new one for atleast 2 weeks. Which means you'd have a extra tank. Ideally you wouldnt house them together as it causes unnecessary stress and like you said bullying. More often then not there will be a bully and a bullied. You leo doesnt want nor need a friend she's alot happier alone. there not social animals in any way at all. But if you just wont listen to reason best way is to introduce them on nuetral ground then clean out the tank where they are gonna live(should be no smaller then a 20 long) getting rid of the current ones scent in every way and re arranging things so that its new to both them....but i dont recommened it... females will fight and can seriously damage one another. Age isnt a factor its the size, you want one thats nearly if not the same size as your current one.

Leopard geckos can be kept alone or together, and will not experience distress if kept by themselves. Groups can be a problem in the wrong combinations, however. Males often fight when housed together, and females sometimes do.
Sometimes, in a group cage, one gecko will grow larger and more quickly than the others, out competing them for food. If this is the case, the smaller cage mates will be undernourished. To prevent this, separate the largest animal and see if the situation improves.
Some leopard geckos are aggressive enough to need to live alone for the entirety of their lives. As these are not naturally social animals, the gecko will not be harmed by this kind of living situation.

Info I found on the web:
FROM WALTER K.--
Adding a female to an enclosure that already has a female is a bit risky but one can minimize the risk by taking these simple steps-

1. Move the exiting female out of the enclosure for at least a half day (you can keep her in a ventilated plastic container). This will get her out of her 'comfort' zone
2. Move the decorations around. Again, this will get the existing female out of the "my house!" mode
3. Introduce the new female into the enclosure and let her get comfortable (about a half hour should do it)
4. Introduce the existing female into the enclosure and at the same time, add food (crickets or mealworms). This will direct both their attentions to eating and not as much to each other

Take these steps and you should guarantee a successful introduction.
