Welcome to the site, Ming-Jieh Lin! I don't recall that we've ever had a contributor from Taiwan before, so it's a real treat

Great pics too! We've had practically no pics or info here about any of the three confirmed species of Taiwanese hynobiids.

That H. sonani looks like a very gravid female! Found her in the water? Does the range overlap with that of H. formosanus? I'm assuming they're sympatric as you have them pictured together there!...

It sure must have a thrill to also find those H. sonani eggs! What was it like where you found them? I ask this because this species was first thought, based on its appearance, to be a "lentic" breeder (laying eggs on twigs and dead leaves or in deep holes in still water), but was later found to be a "lotic" breeder (laying eggs under stones in surface or underground streams). Did you indeed find the eggs in a stream under some rocks?

Have you ever seen H. arisanensis in the wild? This is also said to be a lotic breeding type of hynobiid (like H. kimurae, H. naevius, Onychodactylus japonicus, etc. among Japanese species).

Please don't hesitate to post more pics and info

Hello, Tim, these eggs were found in the stream, but not under the rock. I don't know why.. As other research said, there must be many indiviuals breed together, but just only one I saw at that time~
 
Hai Jieh, happy to see you on this forum too and shed a little light on the 'other' Hynobidae from your region.

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.

    Hello!!! I'm new to this website and idk how to ask a proper question on the designated spot yet, so I'll ask here, I'm a first time Axolotl owner, and my dad used to run an aquarium store, anyways... Orca, my Axolotl, seems to loose parts of her toes on one limb from time to time, I can't seem to find the problem. Tempature is well, she doesn't seem to have any infections or anything, though. And I'm not sure if I'll be able to find a vet in Brazil for amphibians that are in a reasonable distance to drive without stressing Orca out too much

    Hello, I’m hoping for some advice please. Our Axolotl is about 7 months old. Till now no problem. Eating, growing and happy. He’s simply stopped eating. Everything looks fine, his gills look healthy and no apparent signs of sickness. He just swims past the pellets and bloodworm like he can’t smell it. I don’t think it’s a blockage either. Any ideas and suggestions for treatment would be much appreciated. Thank you!
