growing?

About two months ago some of you may remember I bought 3 female baby geckos. Two of them were of identical size and one of them was somewhat longer. Well the two of similar size were housed together and the other one alone, both if which were housed in 10 gallon tanks, with the same temps, hides, bowls, substrate(paper), etc.

Well the two housed together have surprised me, they have tripled there size and there colors are amazing, they turned out to be super hypos, tangerines, with some carotting. I dont have pictures but ill get them this weekend.

My problem is the other gecko, she is not as fat, does not eat as much, and is now smaller than the other two. She is also not as vibrant in color than the others.

Only someone that has raised many geckos can help me with this because its not something very obvious.

can someone please tell me what COULD be different in my husbandry that makes this gecko thrive less?

I may also point out that I have them on a furniture, used to be an old book shelf., the two housed together are on top of the shelf where they get more activity from passerbys an more light from the light bulb on top, while the other gecko is on the last level and almost by the floor. The ambient temp goes down by about 2 degrees only. I dont think this is thje problem, could it be?
