I agree with Kelli. Unless you are really pressed for space, I would house them individually. Its much easier to monitor how much each one is eating (or not eating), you wont have to worry about sexing and separating them in a few months if you dont want to either. Some people neglect to do this and the females end up breeding way too soon which can be very unhealthy or deadly. Also in my opinion, not only do they grow faster but they also develop more brilliant colors. For instance, I housed two females I have since they were babies and they are over two years old now. One has always been bright and the other kind of dull. Well a couple months ago I had to separate them for the first time due to a disease scare and they are still apart now. Anyways, after the first couple weeks of having them apart, I noticed that the female had become drastically brighter! Her dull yellow had turned two or three times as bright. Every shed since then, she has continued to get brighter. I dont know, I guess it could be a "color growth spurt" but at almost 2 1/2 years old I doubt that. The other geckos bright yellow has also developed a lot more orange as well.
Whatever you choose to do Im sure the geckos will be fine. I would house them individually for the reasons stated above, but Im not that pressed for space and people have had tons of success either way. Let us know what you decide to do and how it goes. good luck.
