Hi, I keep a few years ago and paramesotriton paramesotritón hongkonensis chinensis, At first thought they were of the same species but in time I I discovered they were of different species. The issue is that I have about 20 of chinensis and hybrid larvae hongkonensis.


I do not want controversy on Hybrids, I just want to know if any user had offspring hybrida and if the offspring is fertile.

Greetings

I think those must be pictures of the adults - chinensis on the left, hongkongensis on the right.

Can you be more specific?
1. How many newts live together - just the 2 shown in the photos?
2. For how many months or years have they lived together (and was there ever any other newts kept with them)?
3. Have you seen any courtship activity between them?

Newts can retain sperm, so it's possible that the female bred in the past.

I expect that no one can tell you if the offspring will be fertile or not. You will just need to wait and find out.

Odds are they're fertile. The two species are in the same species group and relatively closely related. There are a great many examples of more distantly related species interbreeding with success. In most cases, the barriers to reproduction are behavioral or geographic rather than physiological or genetic.

The photo on the left belongs to the adult female chinensis and the photo on the right the male hongkonensis.
The two newts are about 4 years together, had another female hongkonensis but died a few days of purchase.
I could see how they courted and the pickup of the spermatophore.
Last year the Tritons also laid eggs, They left two larvae that reached metamorphosis to the juvenile stage and reach.The problem is that I had to leave my home because of work and juvenile newts died.
The two species share the same territory triton, is it possible that there are natural hybrids?

It's possible, but none have been reported. Thus far, P.chinensis, P.hongkongensis, and P.ermizhaoi are allopatric. All three species have been considered P.chinensis at one time or another, but all are physically, genetically, and geographically distinct.

Update the pictures, some larvae have already begun to absorb their gills and so far no casualties are about 47 larvae.

If you have enough room and time to give them a good home I don't see why you should destroy them. Just like animals with genetic faults (which don't bother them). Keep them seperated and don't spread them.

I'm a hybrid with genetic faults myself...
