Couldn't the bottom one be more mature tho? I know nothing about geckos. [ Can you tell?] If I dont ask I wont learn. Like how old are geckos when mature? Can anyone recommend a good informative book on geckos? Anyone got a shovel.....
no question is stupid except the one not asked. Geckodan will likely be able to recommend a good book,.
The hemepene bulges on male geckos are quite obvious if you have a female for comparison
Its very difficult to tell from that when they are very small though.
