I am curious when you are able to sex juviniles visually. I am housing 2 together with about a months age difference. Both appear to be males, with the 2 white 'spurs' on either side of tiny [hope I didn't hurt their feelings ] hemipenal bulges. Should I separate them just in case. They get along great right now and like to sleep next to one another. Thanks guys!
P.S.-the pic is of their father

I do believe the fact that they have hemipenal bulges makes them male. Females are without the peen entirely.

I am terrible at sexing geckos via scales and ect...
However I have learned when it comes to bulges ,if you think you see a bulge you probally do ! So if I had to guess you have two males.
As for seperating them it has been reported that cage/cluthmates raised together often get along fine ,even 2 males unless theres a female introduced to them.So you MIGHT be ok...sleeping together is a positive sign.

I meant to add. while you risk a tail....theres a real chance they will do fine together in the same cage.Unless you introduce a female.

both sexes have the spurs and there is very little difference in the size, so you can't use the spurs as an accurate means of sexing crested geckos. If you see a noticeable bulge and from the picture you provided, it is obviously a male. The bulges will not go away if they appear, but many 'females' have developed bulges as they grew older but never heard of the reverse.

Crested geckos can also be sexed by the pores near their vents, but these are very small and hard to see without some sort of magnifying glass. Typically by 6-9 months of age, you can easily sex geckos by the presence of the hemipenial bulge, but for females to be sure, I would wait till 9 months, as some 'females' are late bloomers and suddenly turn male.

I also suggest not to house males together, even if they have been getting along till now. Males can be very territorial and unless they are in a really large cage with tons of visual barriers (ie leaves etc), there is a chance they will start fighting with or without the presence of a female.
