Great news! Since there are now many breeding groups coming of age i expect well see many succesful F2 breedings in months to come. Beware everyone, the laoensis are out to get us!

Congratulations Paul! So this species is considered Laotriton now? I have been running a want ad using Paramesotriton. Maybe this is why I have not had a better response.

Yes. Right from the start it was doubted that they were truly Paramesotriton, and it wasn't long after that they were clearly shown not to be. In 2009, the genus Laotriton was named and assigned to this species.

Basically, they were never Paramesotriton, but that name was used as a convenience until a new name could be definitively assigned.

In fact, you should note that even the forum category accounts for that change. General acceptance of such changes tends to lag well behind the science unless the evidence is very strong and the subject very popular.

How can you be so sure of that?! Every single Urodela page in the web had them as Paramesotritons for months in a row. Can't they have been classified as paramesotriton and then replaced because of its differences? Like they pretend to do with caudopuntactus?

cheers.

xD True, but hey, their chances have encreased dramatically. If just a couple of people succeed, the species is going to see its numbers further encreased. Im hoping a friend of mine (whose animals come from you, obviously) will have luck this year, his males are looking sharp and ready, so its up to the females! Come on ladies!

Why? "obviously"?

I have the exact contrary problem. My female is fat and pointed cloaca but male is not in the mood for it.

@eljorgo: sometimes it works to bring the group up to 18 C for some days, then lower the temperature by changing 2/3 of the water down to 15 C and hold it at 16 C!

Paul - just wanted to say: halleluja and congratulations. Those are outstanding little animals. Some day I want to see one of those in person.

How big is this species? They are pretty hefty newts, aren't they?

Congratulations, and thank you for posting, Paul. It's great to see that F2 has been accomplished - there is hope that this species can become widespread in captivity.
