Need help Sexing CFBN

[AeonMapa]

I could use some help sexing my CFB newts. I'll post several pictures of each I'm sure that will be enough, I have some guesses but I'm not 100%sure so I'd appreciate any help

Newt 1, biggest, somewhat active. "Big Momma". Female?

Newt 2: 2nd biggest, most active. "Mozart" Female?

 

[AeonMapa]

Newt 3: 3rd biggest, shyest. "four eyes" female?
In the last two pictures, the newt hunting in front is newt 5, 3 is the one in the back.

 

[AeonMapa]

Newt 4: tied for 3rd biggest, Very active swimmer, fastest growing. "Tiny" Male?

 

[AeonMapa]

Newt 5: smallest newt, escaped once, somewhat active. "Spots" Male juvenile?

 

[AeonMapa]

Also refer to picsof newt 3 for sexing newt 5.
Also any comments on the general appearance of my newts would appreciated, do they look healthy? They're wild caught, and they seem to have recovered a great deal, looking a lot better than when I got them

Newts 4 and 5 are male. The others are likely female, but it's harder to tell. Yes, they look healthy.

Cool thanks! Are any of the first three definitely female? I was thinking about putting newt 4 and a female in a cooler for a few months to induce breeding

I agree with Jen. Nice animals mate.

You don´t need to cool them, although it certainly helps. This species will readily breed without any significant triggers.

I've read that they need cooler temps and a strict light cycle to simulate winter. Because my tank is usually around 20-22c, I figured it might get them in better breeding condition if I let them live in a cooler at about 15c, in the cooler I can also control their light cycle better. It's a bit difficult in my main tank because I use the lights in my room up till 12am quite regularly. Would you suggest which two newts I should transfer?

 

[Niels D]

My suggestion is to let them stay where they are. We've had our H.orientalis tank at different locations, every one with another conditions and they just kept on laying. I agree with Rodrigo that they do not need a specific trigger.

I just found my female laying her first egg of the season (or the first one i´ve seen, that is). No cooling whatsoever...in fact she always starts laying in late summer/early fall, sometimes with temperatures as high as 26ºC during the day.

 

[Niels D]

That's why I love this specie so much.

Wow at 26c? So basically I just need to keep them healthy and they'll breed eventually? How long would it take a WC newt to recover enough to breed? I've had mine for about 4 months now
