Well my Dobros are at it again. The three females laid nearly 300 eggs in the span of about 3 weeks starting in early December. Out of that original number I have 80 or so larvae who are ravenously chasing down moina and growing exceptionally fast.

The adults have been laying every day but all of the recent eggs have been duds. I have never seen large quantities of fertile eggs before infertile ones before, has anyone else experienced this? The 50% egg die off is to be expected but this is something new.

Here are a few photos of the parents and some of the larvae set ups. Enjoy!

I haven´t experienced that myself. Mine started laying in november and they haven´t stopped since except for a little pause now and then. About 20% are duds in the end alas.

They look great!
Honestly it kind of makes me sad to know that I cant keep this species, dang Washington's rules!!! Such a extensive blacklist.

Keep me updated on the growth of the larvae if you can, I find it all very neat to watch.
Also, anything special you did to get them to breed? Or just keep them "happy and healthy" and they bred?

Congratulations! -Seth

Seth-

The newts are kept in the coolest room in the house and get to high 60s in the summer and cool down to the high 40s/low 50s in the winter. Once the temp creeps up to 58-62 the females usually start laying eggs. Last year they did not get cooler than about 60F and had a much shorter laying season. In my experience a cooling spell is the only "fool proof" way to get the species I keep into breeding condition. Convenient since the seasons do all the work for you.

Your lucky, the temp in the coldest part of the house here ( the basement ) doesn't get lower that 50 I don't think. This morning it was in the low 30's outside and was in the mid 50's inside, in the basement. I don't know why. The seasons would do all the work for me too, but the basement never gets cold enough. Maybe if I remove the my filter that warms the water a bit, that might help.......

Thanks for the info man! -Seth

    That´s the most accurate. Depends on the size of the tub etc. - you just want to make sure the water is always clean

    When little axolotls are tubbed is it common for them to get a little more spunky then usual? Water temps around 64-65 F and has been changed today with prime added

    Hi does anyone know if jungle fungus clear is safe to use for my axolotl? She has some either fungus or bacterial growth on her fillibrae and maybe body and I read that's good to use if you aren't sure if the problem is bacterial or fungal

    That jungle fungus clear. I've been dealing with some fungus with my axolotl on and off this summer. The Holtsfreter solution and water changes just seem to do the trick after a bit

    Where do you get the holtsfreter solution? I've been upping water changes but salt bath seems to be more stressful/harmful than beneficial because she does not like to be caught!

    To raise GH, add calcium carbonate (or tums). What has you doing this?

    Thank you! My tap water is naturally low in GH and KH, and I need to raise it... but I don't want to raise the pH, which is perfect, with coral.

  • AnimeDan:
    Hi Delaney. Can you be more specific? There are lots of reasons for cloudy water, such as substrate getting kicked up, water hardness, etc. if you don’t have hard water and it doesn’t settle then I’d do a water change and see if that helps.
