This breeding took place in an aquarium, but it had some advantages in its favor. Like the water source was the animals' own native cave water, and the temperature was controlled by being in the cave itself. Still, pretty neat. Photos of eggs and video of olm laying eggs at the bottom of the page:

What a great news article with some amazing Olm facts.

Things I did not know before reading:
  • They can stay alive without food for up to 10 years (!)
  • They may live up to 100 years.
  • Females become sexually mature at 14 years
  • Only lay eggs every 6 or 7 years.
  • Slovenia has a coin depicting an Olm

Wow, this is awesome! And look at her/him chilling with the eggs! :3

Thanks for sharing. Would be cool to see them in person one day.

Very cool thanks for posting this! Some of my older published salamander care books have entries for care for the Olm, but I wonder how many private individuals have (or had) kept one of these. I've read that a too sudden increase in light would be fatal. Truly a living fossil.

    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

    Update about my axie, unfortunately he has died over night, he looked as if he was bruised allover his belly, his mucus layer had also started to come off.

    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 :)

    Hi, so I have 2 male axolotls and about an hour ago they were both perfectly fine and now only one of them has his tail curling up and his gills are slightly curled?? But other than that they’re both acting normally

    Could be he's just excited, spooked or temporarily stressed, which could pass in a few hours. It could also be an indicator of other problems. Do you have any recent water parameters?

    Does anyone have any idea how to help with high ammonia levels? I have the API freshwater master kit and everything else’s test results were great besides ammonia. I did a 50% water change and I use API products including ammonia lock.

    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, how big they are? also for substrate, i would not do gravel at all I would either do sand or none at all!

    @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.

    Thank you so much for the information and advice! They are eating again, they ate a lot today. I think it might have been stress from the move or digesting old food, I also noticed they ate some of the food left in the tank (I removed the rest). I’m going to keep the tank bare bottom.
