I know for sure the 3 larger are males, as I've had them for a while now, but the smallest is the one in question. I got it about 5 months ago at maybe 2 3/4 inches. It's just under 4" now.

I bought it thinking it was a male, but as time went on I couldn't help but think it was a female, based on the lack of pearl development on the body and times where it gets extremely dark (pretty much black and stripes where almost no pearling is visible).

My female. Notice the lower jaw is almost like a full beard. Males will not have that out well be more splotchy.

It's hard to tell just have to wait for the colors to come out more. Still very young.
