I have a pair of very young Gold Dust Day Geckos that I have had for about a month. I don't know their age when I got them, but they were about the size of my pinky finger. They have both grown to about ring-finger size (sorry, these are my best references), and have great color. However, one of them is definitely filling out much better than the other, who looks a little thin to me. He's not emaciated, but his spine is more visible than his buddy's, and when he breathes hard I can see his ribs slightly on the inhale. He's very bright-eyed and active, and color looks equally bright on both. Is it normal that some babies fill out faster than others, or should I be concerned about this?
