Hey Jan,
thank you.
Sure i will share information:
I got 2,2 A. tigrinum from a spot in Illinois.
They were in hibernation from November to February.
The temperatures during hibernation were around 3-5°C in my basement. In late February (26.2.) we had about 5-10°C in the daytime so i decided to put my males into an aquarium (100x40x40cm) standing outside.
Aquarium setup: 15cm water, oak leaves, branches, dry sticks and Elodea.
During the first week the temperature dropped under 0°C at night, so the surface was completely frozen. But since 5. of march we have about 5°C at night and 15°C in the day. At 11. of march I put the females into the tank and during night I was able to watch the salamanders mating (at 8°C water temperature)... at 13.3. they were depositing eggs (around 300 from both females)
All adults remaining in water till now.
I got much more notes on that, so if you got concrete questions I'll try to answer them.
Next year I try the same with my other ambystomatids!
But I got a question too: Has anyone bred A. tigrinum (not A. mavortium) last years?
@Rodrigo: What do you like to see?
