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.
 
Yay! Congratulations! I'm really looking forward to the pictures :D
 
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 would say it is a dud because of the fuzz. I dont have much experience with taricha though. That does look like a dud egg though.

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.
 
There are none changing shape yet. Does this mean that my eggs might not be fertile?
 
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!
 
Thanks. I found another one just likeprevious this morning.

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.

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
