The flash highlights the sparkle of the iridophores, it looks a bit less dramatic in diffuse light but the cellar light is not bright enough for my camera. He's still in the temporary mainly aquatic setup as he is only feeding in the water. There is no sign of the other one (a probable female) morphing.

For comparison here is a shot of the unmorphed probable female hybrid, she is getting rather tubby.

Mine look much slimmer than Oceanblue's. Their water temperature is now down to 6 degrees, they are still eating but not so much. Here is a blurry photo of one that didn't swim off to hide :D

The hybrids are fertile ! A friend who received a male hybrid from me bred it to a wild type axolotl and sent me all the eggs (as agreed as they will not be entering the pet hobby). They were layed 30th december and appear to be developing ok. I will be keeping a few to raise to see what they look like.

A brief update, my female is looking fine but the morphed male, now in a fully terrestrial setup is not thriving and looking thin when I see it, it is usually underground. It hasn't eaten as far as I can tell for a few weeks. I'm keeping it cool in the cellar so temperature is not the problem.

These all overwintered in my shed and have been in an outdoor tub for a few months. While trying to evict another invading frog, I fished out some of the hybrids for some photo's. No signs of an obvious male in these ones.

I have an honest question and it may have been answered already but I haven't read through the entire thread.
Why would hybrids be an awful thing in the first place? And why would you cull the offspring just because you didn't want to raise them? Why not explain the situation to someone you know and give the babies that you didn't feel up to raising to them? Maybe I'm too liberal but I just don't understand that logic.

I am pretty sure your question has been answered already on this thread if you read it all.

Thanks for the updates. They have some really nice colouration. I've been trying to get a purebreed andersoni for a awhile now but I dont think they ever made it to Canada.

I didn't realize how pretty Andersoni is. There is conflicting info online.... do they morph into terrestrial form just sometimes?

I had fished out three of the hybrids to clean their tub, so I took a picture of them.
These three have spent winter outdoors in their tub.

I have just put them in with the two that overwintered in the shed and right away they began investigating each other. Visually they could be both sexes, but looking at their cloaca I still see no differences in sexes.

I have kept three in my shed this summer, the other two are in a tub outside.

I had noticed a few months ago that at least one of them was beginning to look like they could be male. I now need to fish out the other two to see if there are any signs of what sex they may be.

thank u all for this topic,
the hybridgene will disolve after some generations,leaving only 2%,its genevigour!!
A andersoni is a more dificult suspecies,it will morphe,when fed worms,also needs good water!!

This is why modern humans have varying percentages of non-Homo sapien DNA ranging from 0% in some parts of the world and anywhere from 2-5% of DNA from at least 2 different species. Some people carry genes from both of the other species.

If not for these crosses, it's likely humans wouldn't have survived in these areas.

Yes, but are there any articles on this, for example a paper written about it?

    I have had my 2 axolotls since June 2020 and I had hoped they would mature the same gender but unfortunately they are not. I am currently on vacation and planned to separate them once I returned, my axolotls are currently being cared for by a friend who knows the basics to care for them properly. A melanoid and a leucistic. I had a feeling but didn't prioritize it enough and now I have many many eggs in the tank with both of my axolotls. I have zero experience with eggs and cannot really care for juvenile axolotls but I really DO NOT want to kill them. What should I do? Are my axolotls okay being in the same tank with them? would the eggs be okay all together in a tank by themselves? Where can I find someone to care for them and hatch them?I'm so stressed and worried I just want the best for them all.

  • axie owner:
    you are going to have to get a bucket and put the eggs in that. they can hatch anytime between 11 and 20 days. order in brine shrimp eggs and get your friend to watch a video on hatching them. make sure your friend does 100% water changes every day. keep the water around 64digres and make sure your friend sends daily updates on them. i found kitchen salt works for the brine shrimp eggs. hope this helps.

    Hi guys.. I might of made an error and need some advice. One of the hides in my tank is too small for my axie now, but I did not want to buy another hide because they are expensive, so I decided to DIY one. I used a Tupperware (cut into a little home) and glued rocks from outside and plants on it. The problem is, I washed the rocks with soap and hot water. I completely wasn’t thinking. When I washed them there was no soap residue that was visible on the rocks, and the rocks have been drying for 3 days on the container. So it has been 3 days since I washed them. I used aquarium safe silicone to glue them on. It was fully dry tonight so I decided to put it in my tank. I had it in for about 3 mins until I realized j had washed the rocks in soap, and I took it out immediately. Should I be worried??? I’m really freaking out, I don’t want anything to happen to my baby! I was truly not thinking. I also read that it was safe to use rocks from outside, but now I’m not sure? Can anyone help

    @Paige1warren, Since you took it out straight away it should be ok but I'd still be doing a big water change. When I was a teen, I took some rocks from outside, washed them (probably in soap) and put them in my turtle tank. He died a week or so later and I've never used any rocks from the garden since because you just don't know what's been on them, such as pesticide and I suppose the mineral composition of the rock comes in to play too. Letting them dry for a few days before adding them also would have helped so you should be fine

  • Toothpickthelotl:
    @Saturn, okay, thank you so much! Firstly, I’m so sorry about your turtle :(. My lotl seems to be fine, I haven’t noticed any changes or signs of destress. I do 25% weekly water changes (I have a fully cycled tank), but I will do a 50% change today. I hope that everything turns out fine. Axies are pretty good at showing they are not well or stressed so I’m hoping that I got the rocks out fast enough. Thank you again!

    Can't say if this is what's being referred to, but I had some ceramic tiles in an aquarium for a while. I used a silicone sealant to secure them to the bottom and to each other. It worked well for about 6 months, but eventually a little water got through my imperfect seal and started creating mold problems
