Hello,

can Nephrurus be temp. sexed? I incubated 4 eggs of N. levis levis at 27 °C and got 4 males. At what temperature I get females? And how is it with the other species?

Best regards

I hatch all nephr at 27C and gets about 50/50, males/females.
I met a man in Hamm last time who claimed that amyae could be temp. sexed, but he was selling a few days old hatchlings and all where labeled females...........hmmm

In my opinion they can´t be temp. sexed and 4 males in a rowe is just pure bad luck, but there will be moore opinions I belive.

Cheers!

It is nice to hear other breeders opinions and experiences. I assume that is was bad luck too. But from what I can tell, you can sex them as early as 2 weeks. Thats truly possible. Males have a line or small groove, which will "devide" later the two hemipenis. While females don't have them.

@Pitbullgeckos

How do you incubate the eggs? (Temp., medium, etc.)

Nothing fancy; 27C, perlite + water 1:1, a few small airholes in the lid of the container. If there builds up condesewater on the lid I take take droplets away.

But there are probably many ways, but thisone worked for me

What size of container do you use? As I made experience, that too small containers with little amount of perlite dry out very quick.

sofar my experience gives me also the opinion that nephrurus are not temperature sexable, you just have to be a little lucky.
but the ratio is often about 50%.
i use small containers with vermiculite (1:1water)for the eggs and keep them closed so no airholes.
that way you wont have condence drops on the lit wich can fall on the eggs and the substrate will never dry out.
once a week i open them up a short while for some ventilation.

" Males have a line or small groove, which will "devide" later the two hemipenis. While females don't have them."

Wich species are you talking about? N.amyae? In my experience, both sexes present that groove and I can sex them only at 10-12 weeks old..

About N.l.levis, I sex them at birth but with the other subspecies of the N.l.levis I have found it to be a bit more trickier..

@kanopy

I'm talking about N. l. levis. I was not 100% about sex directly after hatch. BUt I was 100% sure after 2 weeks. With the others I need also 2 1/2-3 months.

At which temperature do you incubate the eggs Fred?

[kanopy]

Hi Magnum,
I incubate at 27-28°C and get quite a balanced ratio.
