Well, last night I came home and found my female laying eggs. So far we have counted a couple, but I hope there are more to come. They have been mating all winter, and now they have something to show for it. I have to go to school, but will post some pictures and more specifics when I get home.

Here are some pictures. So far we have counted 7 eggs. I really didn't do too much to get them to breed. The temperature this winter has been around the low 60s. I have a flourescent light that I turn on when the sun comes up and turn off when the sun goes down. I feed them earthworms, but this winter I ran out of them so I got frozen bloodworms. The plants are also plastic. There are some pictures of them in amplexus here: http://www.caudata.org/forum/showthread.php?t=59111

Super, I'm very happy to see this! How many adults do you have?

That's great news, Will! A lot of people see amplexus, but few ever find eggs. Good luck raising the larvae.

Interesting. That's the same number of adults that Audrey has kept together; she's also been successful getting eggs from T granulosa. This could be coincidence, or it could be something that's significant in breeding this species.

Which would be really unusual since that seldom ever occurs in the wild!

Here is another picture of the eggs. The one on the left seems to be a dud. What do you think?

I agree - the left one is a dud. The one on the right is ambiguous; it's either a fertile egg, or it's too soon to tell. Do you have any that are clearly developing (changing shape)? In 2-3 days it's usually fairly discernible.

Here's a strange photo. It seems like there are 2 embryos in 1 membrane.

It happens now and then that there are more than one embryo in one egg but most of the ones I've seen are separated by another membrane (that is hard to tell with the photo).

And late congratulations to the breeding success!

I don't think this is significant, I've always kept them in groups (3,4 at the Moment) and bread them every year.

Well, I'm starting to think that these eggs aren't fertile. I have not seen any clear signs of development and it has been a week since she has started laying.
Edit: Scratch that. I'm almost positive. :(

Not necessarily,

I keep 2,2 and they breed since years very well.

    Can anyone answer if I can use trichlorfon 20mg with my axolotls to treat the anchor worms it is supposed to kill them. I have purchased something from the shop called blue planet paracide which has 20mg of the trichlorfon

    @The-Axolotl, im a hug energy when it comes to axolotls, and decided i might as well “shoot my shot” and try to make a living out of it. lots of inspiration taken from margie, who used to breed and sell here on caudata- she was raising about 1000 juveniles at a time, which is my end goal

  • Elder_Axolotl:
    @Albi_the_axolotlt I would definitely make a thread about this, but before you panic try putting you axolotl in a tub where the water only goes about an inch above it, and then cool the water down SLOWLY, like a couple ice cubes at a time, to about 50 Deg F. sometimes this helps them pass gas, or even have a bowel movement. Just make sure the Temps from your current enclosure and the tub are within 4 degrees of each other and not higher than 65 Deg F. so you dont Temp shock your baby.

  • Albi_the_axolotlt:
    well I don't know how to make a thread and I am very thankful for your help but the real reason I am worried about is that it goes away and comes back constantly like its gets better today then tomorrow morning she is at the top of the tank floating on her side all bubbled up? I do put her in a container with just enough water to cover her back and it helped but it gets annoying and scary when it's consantly happening and I am worried I am doing something horrible wrong.
