Hey,

the first four entered the land.
Here's a picture of the first two:


The bigger one was the very light coloured larva from my post before.


The metamorph on this picture is from my outside-tank. The colour is very different to the others from inside:


Let's see how they develop ;)

This is great! We need more tiger breeding.

Well done!

More than half of the larvae morphes in the meantime.


Here are 22 of 26 metamorphes I got so far.


Some got a spectacular colouration for A. tigrinum from that location:



The smallest and the biggest metamorph together. 8 and 16cm in total lenght (about 3 and 6'')

Holy FSM, Mario, you are on a roll! xD
This indeed seems to be a fantastic year for ambystomatid captive breeding. I have the urge to do a little dance.

Congratulations! But when does it become captive breeding versus letting them breed naturally?

It comes to captive breedings when you keep a species and they breed? :wacko:

In my opinion natural breeding occures in their natural environment without people telling them when they have to live in an aquarium or on land :D

Hi
I am also the proud owner of the same locality of tigrinum.
The story starts back in 2011, where I got some eggs from Martin ( Megs) and placed them in a tank in my wintergarden. They developed into newt quickly, and started to grow and grow. Unfortunately we got an uexpected hot day while on work, and when I came home all larvae was upside down. 4 of them still had a little movement in the gills, but the rest was dead :mad:
In the panik the only solution, I could find was to throw the tank out into my pond in the garden. Weeks became months and I didn`t see any of them again, so I expected they were dead.Then one evening in the late summer, I was sitting next to the pond enjoying a cigaret and a beer, when a huge swop sounded from the water. Hmmm what was that? While looking there suddently came a monster up to the surface and took some air........ I tried to catch it, but witout luck so the next day I emtied the pond and in the mud I found 2 larvae ( a pair ).



They were really big. 21 and 22 cm.
I placed them i a large tank, but they emidiatly started to reduce the gills and went on land in a few days.



Later I got the parent animals too, but they were much smaller than the 2.

A few days back I placed the adults in a tank outside. The males 1 day before the females and I tried with a seperate tank for the "homemade" pair. The next day the first eggs were deposited, and they are going on and on. I theink there are about 300 now and I really hope they are fertile.



Best wishes

I actually gave up hope on the eggs, because I didn`t see any development. Then 2 days ago I looked on the eggs at the 2 of my own breeding and within the soup of algaes, I saw this:

Today the last larvae have left the eggs. Unfortunately only in 1 container, but a fast count passed 80, so there will be more than enough to feed on:happy:

Status from today:
About 80 -90 left in size from 4,5 to 10 cm. I have had serious problems getting enough food for them. I tried feeding with pellets and frozen mosquitolarvae, but the only result was, that they went into canibalism :mad:. I needed to seperate them in size on a daily basis, so now I have 5 tanks with larvae. Problems started at about 4 cm, but the large ones have now stopped eating each other.They are fed on earthworms and soldierfly larvae and gives no problems beside all the water changes.
I finally found a pond with live mosqutilarvae and daphnia yesterday, and for the first time in weeks they didn`t eat it all up before next morning.
I hope I will manege to get the rest past 8 cm, so they can be fed on worms in stead. That is far easier.

Made a new setup....... I was fed up changing 1 m3 water a day, so I made a rack where the water flows from one to another and then back to a container filled with water plants to remove the waste material from the larvae.



I also gave up catching and digging food enouh for the "Lock Ness" monsters so I started on buying 5 kilo earthworms.................That will last a few weeks ( If I am lucky :mad:)

These buggers eats me out of the house and the grow like madness.

Lets see how big they grow. My goal is a larvae at 20 cm and hopefully 25 but I recon thats impossible

    @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.
