Re: Ambystoma maculatum

These are all growing at different rates, with some being more advanced than others. You can just about see the balancers on this one.

Re: Ambystoma maculatum

My first larvae, plus one thinking that reversing out may be a good idea :eek:

Re: Ambystoma maculatum

Unfortunately I lost the few larvae that hatched :(

I was looking on another forum today and saw a UK gentleman has just had eggs laid from his group. I hadn't expected mine to do anything for a couple of months, as my last lot where laid early April after a rather cold spell. This winter has been rather wet and mild with only a few slight frosts here so I wasn't really expecting to see anything at all. Today has been rather mild and it had just started to rain again, but I thought it was worth trundling out to the shed to see if they were up to anything. I didn't find any eggs, but I did see plenty of activity from them. One was hopping in and out of the water and the floor of their tub has scattered groups of spermatophore :) I now have all fingers and toes crossed for eggs :D

Re: Ambystoma maculatum

Day 8... and not much has changed. I have left the eggs in where they were laid this year. The water is maybe 8-10 degrees C.

Re: Ambystoma maculatum

How did i not see this? Congrats Julia! Fingers crossed they are fertilized and they develop well. And even if they don´t, congratulations are still in order for a repeated success in getting them to lay!

Re: Ambystoma maculatum

Thank you Rodrigo :) If I look really really closely at them, there may be some development, but after last years shenanigans I am trying to be less of an egg watcher this time ;)

Re: Ambystoma maculatum

These are taking forever to grow :( Hopefully the temperatures rising towards the weekend, will encourage them to grow a little faster :).
Anyway, photo's of day 26, the water temperature was 5 degrees.

Re: Ambystoma maculatum

Day 35 and the day time water temps are on average 11 degrees now. If I look really carefully I can see eyes, balancers and gills. I would think the first ones will hatch in the next few days. The pictures are not so clear now as they egg mass is looking a tad grubby and I can not get the camera to focus through to the larva. I took a few of the ones underneath today as they looked clearer, but the pictures came out distorted . All the larva, barr one or two all look well developed. Only one in the middle turned white , much like last years and one is only now looking to be developing.

Re: Ambystoma maculatum

I didn't Dawn, they all died quite early on. This time I am leaving most of them in the main tub as there looks like there is plenty of small food ready for them.

I couldnt get them out without a turkey baster and decided to let them sit because i was gonna move him to the house tomorrow. But now its late and I dont have a car and my dad wont drive me. Will he be fine?

    Hello everyone! I’m new in this world and i need some advices please! I have 2 axolotl babies and currently the water from the tank is from bottled water ( all parameters are good) but i want to change 50% of the water with city tap water. My question is how to change it? Do i need to get axis out, do the change, add the prime, wait (how much?) until its dechlorinated or i can add the tap water directly into the tank with axis in it, and add the prime conditioner? Thank you!!

    1. You dont need to take them out of the tank to change the water as long as you pour it in slow as to not rattle them around too much
    +1
    Unlike
  • Asmold1:
    2. add the prime to your tap water, for most conditioners the consensus is 5 minutes of waiting time
