Hello it's Paul from France,

I'm very surprised and a little proud that my thread started in 2005 is still on the board as a sticky thread, and the picture still on line:

http://www.caudata.org/forum/f1173-...p-etc/39760-ambystoma-mavortium-breeding.html

it seems I may be was one of the firsts to breed the A.mavortium, WOW !

my english has not really improved so excuse my grammatical mistakes...

Well,

I'm still breeding my salamanders, F2 now, but still looking for new species and sub species, very hard to find in France...maybe now I will have some help from internationl, european breeders that succeed in breedings...


larvae a few weeks ago ;-)

well image hosting is working ;-) but only 3 at a time with the attachment option ?


i have a hundred larvae, raised in two separate tanks, one indoor, the other outdoor,

on the last picture you can see the size of the larvae to the right the biggest one ( 6 cm)
at the left average size from the indoor tank, in the middle average size from the outdoor tank,

i feed them with daphnia ( as seen in the pictures)

Thank you for adding the pictures Paul. It is lovely to see them.
What type of setup do you use for them to bred?

Hello ;-)

temperatures are very high in this month of july, almost 30°C here in the north,

and today I found 2 larvae starting to metamorphose, shape is changing, less fat, color is changing too, more spots, and gills are reducing...

on the first pic you can see the difference between two larvae

Hi Paul
What size are the larvae now?
Mine are up to 13 cm and no signs of reducing the gills yet

Hello Soe, my larvae are about 10 cm,

these two are precocious I think may be due to the high temperatures (30°C)

they usually metamorphose when 12/13 cm,

sometimes some don't metamorphose the first year and then they metamorphose when 16 cm

the level of water in my tanks is 5 cm

;-)

Thanks for the "likes"

Metamorphosis is accelerating,

10 larvae are changing, the precocious don't have gills anymore !

how can I make my pictures to appear in full size (800x600) in my post ?

Lovely pictures. I hope to breed mavortium next year or at least have a few fertile eggs to work with. I still hope to make a real "Godzilla" and not just a 20 cm larvae. I recon it is impossible with tigrinum but maybe possible with mavortium or diaboli. My tigrinum are still not transforming, so I hope at least 1 will be 20 cm before metamorphosis.

Here is a pic of the mavortium that could be the next project. They are huge and 3,1 so it might be possible.



Best wishes
Søe

Beautiful mavortium ! the tail looks very strong !

How do you manage your picture to appear full size on this board ?

How and Why your tigrinum larvae don't metamorphose ? are they neotenic ? any signs of transformation ?

Hi Paul.

I place all pics in a folder on my webpage after reducing their size to 600 pixels and also down from 4 MB to 100-150 kb.
When I want to add them to a forum, I do as follows:



Thats the only way I know of, but I am also a dinosaur on a computer.

Conserning my tigers there are news. Yesterday I saw that one of the animals has reduced its gills. Not one of the biggest, but only a 15 cm larvae.

So it should start now. I am both happy and sad. Happy because I don`t to feed and change water so much. Sad because I don`t think I will reach a 20 cm larvae

Pic will come up on Marios tiger tread.

    @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
