Lol! Wow, he's that tiny? I don't know exactly how old Castro is but he's definitely small, i'd say less than 2 inches.

Oh and another question, do they tend to darken as they age? Well I have only had Castro for about 2 weeks and just 2 days ago I pulled him out and noticed that he turned a slightly darker grey. ??????

Yes, they do darken as they age. Yours could be going into shed, which would explain the graying color.
