I read in Ed's caresheet for this species at Caudata Culture that "at this time, there are no substantiated reports of captive breeding for any terrestrial forms of A. tigrinum or A. mavortium."

Today I had a visit from Mr. Masai, of Japan, who has successfully bred A. tigrinum mavortium (WC to F1, F1 to F2). I received one of those larvae from him through a third party a couple of years ago (though I failed with it).

I've scanned the pics he showed me and will post them here in the coming days.

But please don't ask me for the details of how it was achieved as I simply don't have them (and I don't know much about Ambystoma to begin with!). This is something he's willing to document in greater detail (the next breeding round is in the spring) and share with us. But he'd prefer to present it as an article for Caudata.org magazine

That's quite a breakthrough, Tim! Tell Mr. Masai that MANY people are eagerly awaiting his article!

Here's an F1 female laying its eggs:

I'm sure he'll be happy to hear that Jen




By the way, should this be A. tigrinum mavortium or A. mavortium?

i like the use of the notebook binder spine to fan out the plastic strips.

I think the care sheet will need to be updated....
(and that care sheet was the effort of three people so I do not deserve all the credit, Jen and Nate had a lot to do with it.).
I am very interested in the details also as the methodology should apply to other Ambystomids.

Paris, it's not a notebook binder but a heater cover.

Since this seems to be his original idea, it seems only fair to virtually patent it here as the "Masai method" or "Masai breeding nest" or something like that

Tim, please tell Mr. Masai that I am greatly looking forward to it!

I shall pass that along


Here is a pic showing the 700-800 (F1, I think) larvae, all from the same female:

Simply amazing. To be able to bred tigers is a major breakthrough for the survival of this endangered species. Hopefully, Mr. Masai's method will be compatible with other species of caudates, especially those whose survival is contingent on captivity.

Ben, I don't recall. I think he said he has 40-50 F1. Or was it 40-50 F2?

Here is a pic of what I think is the F2 larvae:

A close-up of the same:

Tim, unless he's maturing tigers in a year, I am guessing those are from the same parents as before. If that's the case, the larvae aren't f2, they're also f1.

I'd give my right arm for some of them.

Ah, but of course. I didn't consider that rather obvious fact
I think it's probably better if I just post the pics and hold off the detailed narrative until I can confirm facts with him. To some extent, the dates shown on the pics speak for themselves.

Speaking of right arms (and left ones), here is a pic of the larvae with their hind limbs having developed:

I find barred tigers to be simply beautiful. Please thank Mr. Masai for letting us see his tiger world ;).

    @ChocoUniversa, Buy some ammonia and an eyedropper from Walmart and a water test kit for ammonia, nitrites, and nitrates. Figure out (through testing) how many drops it will take to get the ammonia level to the test's maximum measurement. Add that same number of drops every 24 hours. Eventually, the ammonia will start to go down as it's converted to nitrites. Keep adding ammonia. The nitrite levels will spike for a while and then they too will start to go down as they convert to nitrates. These you get rid of by doing water changes, which you should be doing anyway throughout the process. Once all of these are at low levels, your aquarium is ready. It takes about a month, maybe two (mine took a month and a half). Be sure to add ammonia until the day of or the day before you add your axolotl.

    Hey guys, this is my first time using this so bear with me. I have an adult axie who looks like he’s developed some fungus on gills. It’s still really small and only on one part. I put him in a 10 gal quarantine tank with an Indian almond leaf. I want to give him a black tea bath but not sure if I can add my black tea to the tank with the Indian almond leaf in there. Any advice?

    @XxJennXx, I don't believe so. They are closely related to tigers and my tiger doesn't brumate. I think first year they might but after they see they aren't needing to, they should be good. They might try and hibernate to, mine did for the first year but now I see him crawling around right now.

    @Pookisoo, The refrigerator is a good hospital for tigers.Temperature between 7 and 2 degrees Celsius can stop bacteria. If necessary or if you dare 0 to -2 can also help.Reduce the temperature in a few days from 7 degrees to 2. After that you can reduce further. Feel free to let it sit for a few weeks. Place the animal in a plastic container with a lid with some air holes. Fill it with some soil and / or leaves. Check regularly whether there is still moisture or ice in this container. At temperatures above 2 degrees, they do not go into hibernation. They will then live on their reserves. Doing nothing is not an option, I speak from experience. You can avoid these kinds of problems by keeping them fairly dry for much of the year.

    Hi guys! I’m new to this site and a new axolotl owner. I’ve had my baby (his name is toothpick) for about a month or so now. I finally got a water testing kit and I tested the perimeters earlier today. My ammonia was at 3 ppm and my nitrite was at 2 ppm. This freaked me out because I know they are supposed to be at 0 ppm. I did a water change a little bit ago and it went down to ammonia 1 ppm and in between 1-2 ppm nitrate. I change 50% of my water weekly and clean up any pieces of waste or excess food with a turkey bastwr everyday. Could this just be because the tank isn’t fully cycled yet? Should I be concerned? Toothpick hasn’t shown any signs of distress

    @Paige1warren You need to tub your axolotl and perform 100% daily water changes. Your tank is not fully cycled, and any readings of ammonia or nitrite are toxic and potentially deadly. A fully cycled tank should at all times have readings of 0ppm ammonia/0ppm nitrite/0pmm<nitrate.
