Hi,

My C. Orientalis female layed 5 eggs on the digital thermometer on 27.10.2010.

The female is actually 8 cms long ( largest in my 4 newts ) and hence did not expect her to lay eggs so early as I thought the females have to reach 10 cms to start laying eggs.

Am enclosing few photos of the eggs. Would like to know if they seem to be developing. Checked on the site but could not locate any photos of developing eggs.

Do let me know if these seems to be healthy and developing. The third photo is taken on 29.10.2010.

Regards,

Are you absolutely sure they are Hypselotriton (Cynops) orientalis? I´m just asking because this species lays eggs individually on submerged vegetation. I wouldn´t expect them to lay on plastic thermometer and re-use the same spot. I suposse it´s not impossible if there are no suitable laying places, but it´s certainly very weird.

You should offer adequate laying substrates like live/fake plants or plastic strips if you prefer.
The eggs look like they are developing, by the way, so they should be ok.

Just to remove the doubt, females don´t need to grow to 10cms before they are able to reproduce. In fact 10cm long females are rare, they don´t usually grow that large. Generally speaking, i would expect any female larger than 6cm to be able to reproduce.

Hi Azhael,

Thanks for your reply. I think the newts are Cynops Orientalis - I have no other newts. Am attached a few photos of the newts so that you can confirm them for me.

About the choice of place for egg laying, there was no other option for her in the tank hence probably she used the thermometer.

Am not sure if I can handle more eggs hence will not put the plants as suggested by you, keeping the temp cool enough here is a challenge. The room temperature is between 30-32 C.

Will concentrate on trying to hatch the present lot.

Regards,

Hi, I am no expert but I think you should give the female something to lay the eggs onto. She will need to get rid of them. You can just leave them in the tank if you don't want to take them out and raise the babies.Just let nature take its course (parents might eat the eggs or larvae, there might not be enough food in the tank...you probably won't end up with dozens of newts this way). If you want to have some little newts for sure you should definitely take out more than just 4 eggs anyway. Making brine shrimp or something similar for 4 larvae would be a bit strange. Don't forget that a lot of larvae will not develop well and will die later.
Have a look at the Reproducton & Rearing articles here:

They definitely are Hypselotriton (Cynops) orientalis. No doubt.
It´s very weird that she chose that place to lay.

Even if you don´t wish to raise more offspring, i would allow the female to lay her eggs. Technically they can reabsorb them, but it would be best to let her lay them. As Eva says, they may eat them, some individuals are big egg-eaters.
If you leave the larvae with the parents, it´s likely that only a handful would make it metamorphosis unless the conditions are particularly excellent and food is everywhere.

I´m sure you know this, but i would make a serious effort in trying to lower those temps. If the water temperature gets close to that, it can be lethal to your newts.

Looking closely at the 3rd photo, I'm not so sure that they are developing. To me, they look like some of the duds I've seen.

I agree with Jennewt, those definitely look like duds in the third photo. My newt was about 7 cm when she had her first batch of eggs, and now she's about 9.5 cm. She's a big girl. : P

I´m not that sure, there has obviously been celular division, and i think one looks like a basically normal embryo. There are two that look like something went wrong in the process, but i guess only time will tell.

Guys,

Finally some eggs have hatched !! :happy:. Some photos that I clicked, the larvae are about 2 weeks old.

I have been feeding them live daphnia and also the smallest of tubifex worms that I can separate from the large ones. I have not seen them eat though their size is slowly increasing.

Regards

Some more photos, the larvae are now a little more than one month old and about 2.5 cms long in length. They are eating small tubifex worms and little bloodworms.

Hey,

Congratulations.
I've just got one question : I can't see any plants on the pics of your adults. I hope they have some. Normally, the cynops orientalis female lays each egg on a leaf and pulls the leaf around it. My female lays like 60 eggs within a few days... but each and everyone is wrapped up in a leaf not like yours left behind on some surface.

Take good care of the little guys. You will have to provide them with a possibility to get out of the water when they go into metamorphosis. Of you don't they will drown. They go terrestrial for quite a few weeks/months before they go back into the water (if at all... some don't, really).

Good luck and have fun and keep posting piccies :)

Barbara

SwissAxie, Jennewt, Azhael,

Thanks for your kind remarks.

Barbara,

You are correct I do not have any real plants in the adults tank.

Actually in India, newts are not very commonly sold in the petshops and very rarely you get to see them in the shops. I was on lookout for these for several years now and finally got 4 of these in a local petshop. When I got these newts they were very frail and weak to look at and hence I preferred to keep them in a bare bottomed tank so as to monitor them better and nurse them back to health.

I was not aware of the Chinese species till I brought them home under the impression that they were the japanese species. This site helped me clear the doubts and confirm the species to be cynops orientalis.

I did not expect them to lay eggs so soon and so was caught unaware, the first time the eggs appeared on the digital thermometer. These did not hatch and hence I put a small artificial plastic plant created out of plastic strips. They soon layed on this plant and I have still some eggs developing on it.

I do intend to build a larger tank 48 x 21 x 21 inches wherein I will have some land area with live plants and real aquatic plants in the water part.

Also before I build the large tank, I have a 32 x 16 x 16 tank which I will intend to setup before to check the cooling and water currents created by the water circulation.

Will put of the pictures of the process soon.

Look forward to your comments and advice.

Thanks & Regards,

The first morph of the the lot spotted today. Attaching a few photos.

The first egg had hatched on 29th Nov 2010 two months back so it took 2 months for the metamorphosis.

I have shifted the little fellow to a small container kept tilted along the side with max water depth of 1.5 cms.

When do the undersides start turning red ?

The morph looks great, well done rearing them through. The underside will not turn red unless there are (plentiful) carotenoids in the diet. The biggest effect is had on larvae (with Daphnia, Artemia and other crustaceans being particularly good sources), but if you feed the juveniles with supplemented food stuffs it will help to redden the belly. Gut-loading crickets on raw carrots works well, but commercial supplements are also very good for both gut-loading and dusting on food items. Rodrigo (Azhael) knows quite a lot about this, and there is also information at Caleb Leeke's site, here: Carotenoids and amphibian colouration

Best of luck with the morphs

Congratulations AmbhiMan. Just judging by the size of these young newts I can tell you have been feeding them regularly.

Froggy , anothernewtfan,

Thanks for your kind comments.

The length of this fellow is around 4 cms. I have others who are close to morphing and around the same size or so.

Will post more photos as they develop.

    Hi I recently rescued a lotl (i did weeks of research before rescuing) Hes mabey 5 or 6 years of age..the previous owner could not remember the exact age of him. I got him from her as he was or had been picked on by his tank mate another lotl who was bough with him from every younger age, I noticed one of his gills, a middle one at the end had split in two? And is slightly more floppy? He also appears or mabey I'm just over worried to mabey have lost some feathers, is that normal to lose some?...all levels in the tank are fine, but wondered if theres and advice anyone could give me as an experienced owner to a new one.

  • Axolotl Queen:
    @Lanalotl Sounds like the gills may have been nipped by the tank mate. If he is in his own tank and the parameters etc are all good, then he should grow them back and they should go back to full health and strength. However, depending on how old the injury is they may not fully grow back if they have been constantly nipped at.

    Can anyone tell me why this is happening? We just did a water change and after freaking out and whipping around the tank, an hour later they look like this. It won't let me send a pic. The edges of their gills are white and it looks like they have skin shedding off

    It sounds like something went wrong with the water change, so this could be very dangerous. Did you use a dechlorinator? Could it be there are traces of chlorine or soap in the water? (Or for example, in the bucket you used?)

  • Murk:
    Normally, I would recommend taking them out of the tank asap and putting them in a tub with fresh water, but if there's something wrong with your tap water or dechlorinator, that might not help either. Do you have acces to bottled water or rain water?

    I think my axie is dying, he’s never had any issues before, I’ve had him 3 years, today I noticed some fluffy looking stuff coming from his genital area so I took him out of his tank and did a full tank clean to make sure the water wasn’t infected as I thought it was fungus and then I noticed he had a cut on his belly which was only small about 5 hours ago and now it’s spread to all of his belly, what do I do I’m freaking out

    Hi I have 2 4in juveniles (I’ve had them about 2 weeks and they are doing well I think they’ve grown a little already honestly) but I am supposed to go on a 5-6 day vacation in October about 3-4 months from now. I am wondering how I should go about their care when I am gone. I thought about putting them in separate (fairly big) containers with live plants and/or bubblers with a fan in the dark and either fridging them (my last plan) but I am hoping to to either have someone I trust come feed them and turkey baste waste out or just leave them out and clean the containers before we leave and have someone come check on them once or twice. Does any of this sound like a good or bad idea? I want the best for them. All help appreciated :)

    Help! I got my first axolotl two days ago and they have stopped eating. They ate a few frozen blood worms the first day and haven’t eaten or been interested in food since. I feed them frozen blood worms and the tank is around 64 degrees. I do have a filter that moves sometimes and I noticed them swimming up to it, I have a new filter and a fan coming today or tomorrow. I leave the worms in the tank or a little bit before taking them out so I don’t know if they ate when I wasn’t looking. I know it takes a while for them to digest. Does anyone have any tips or knowledge they can share? The pet store I bought them from didn’t have gravel or sand in the tank so I’m not sure if theres an issue or if I’m just impatient. Thank you!

    @MuggleMiChu I would say try live black/blood worms untell they are full or just turn there head away ( that's what mine do) if that does not work try to get some live brine shrimp and see if they eat that. baby axolotl prefer live food over frozen food as the frozen food is too cold for them or they can't eat it in one go( that's if you do the blocks) mine eat chopped up frozen thawed shrimp. as for them not eating from what I have experienced with my second axolotl, I got her when she was about an inch long and she ate every day, when they start getting 3-4 inches long they will gradually slow down there eating. and if you really want to do substrate I would do sand because if they do ingest a little bit it won't hurt them.
