Ambystoma macrodactylum: Successful breeding

[MarioR]

After Rodrigo asked that nicely for some pictures in my tigrinum-thread, I show you what also happened in here:

I got a group of macrodactylum macrodactylum with 7 individuals. All are CB'09 and mature now. They measure about 10cm ttl.

Eggs:

Possible parents:

I used the same technique as I descripted in the linked tigrinum-thread, but I threw both sexes into the outside tank at the same day on 3rd March.

Greetings,
Mario

Thanks for sharing

It´s great to see the F2 of this species in captivity. It makes me very happy to know ambystomatids are being bred more or less consistently out there

Hi Mario!
Congratulations!!
you'll want to sell them after matamorphose?

 

[Jan]

Big congrats Mario on your continued successes!

 

[MarioR]

Thank you guys!

@Thomasz: Yes I will sell some after metamorphosis.

Regards,
Mario

I think we're at the end of the story: All eggs i collected (127) are infertile...

 

[Azhael]

Aaaaaaaaw....that´s a real pitty, sorry to hear that, Mario, you have my condolences.
At least you have managed to get them to breed once, so the future is looking good. Things like this are part of the psicological hazards of this hobby.

It was a good try, much farther than I've ever got in my limited expierences with A. macrodactylum

I know how disappointed you can be after discovering that a batch of eggs is unfertile in the end. Experienced the same thing with my Gastrotheca riobambae, because all the eggs in the female's pouch weren't fertilised. Luckily you're tigrinum eggs are a succes! After reading your thread I immediately changed my setup for my tigers into an aquarium like yours. Sorry for being such a copycat...

Let's try it again :happy:

News update:
Most embryos develop well and are shortly before hatching after 10 days.
I added new photos on my homepage: Ambystomatidae - Die Welt der amphiben Maulwürfe
You can also see the balancers of the embryos which distinguish them from most other Ambystomatids.

To my pleasure my second group with known locality laid eggs at night too :ha:

Regards,
Mario

Best of lucks, Mario! Wonderful pictures, by the way.

One month after hatching the biggest ones are 3cm long and grow their hind limbs.

They are nasty cannibals and seem to love the front legs of their siblings.

Unfortunately all eggs laid by the second group were infertile - just like last year

Mario

Ambystoma macrodactylum larvae are the prettiest Ambystoma larvae I ever had.
