hi everyone, i have a few questions.

one - i don’t have any daphnia/BBS in my area, and i’m hesitant to buy online because i‘ve seen very mixed reviews. i’m only keeping 25 eggs and culling the others, and i was wondering if i were to manually take each hatchling (not like pick them up, just have them separated) and wave bloodworms near their face if they would accept it?

two - if the mother is gfp and the father is not, what are the odds i have gfp hatchlings? also, can you tell if an axie is gfp by shining a black light on the eggs?

three - do newborns//hatchlings need a filter? i know you have to change the water daily (or more than once a day, depending on feeding schedules and how messy they are) but i haven’t been able to find anything on filtration. i’d use a sponge filter, but i’m still concerned.

that’s about it, if i remember anything i’ll be sure to post it here! thanks everyone :)

Hi !

I'll try to give some answers, but sorry, not all :

One - axolotls hatchlings generally accept only small living (moving) preys.
I agree that buying daphnia online seems risky. You could try to find brine shrimp eggs (you can obtain BBS hatching within 2 days).

Two - sorry, I know nothing about the GFP gene and how to diagnose it, but I'm sure someone on the forum has much more knowledge than me.

Three - I've never used a filter with the newborns/hatchlings (18 years without problems). Changing the water often is enough.
With only 25 newborns, you can keep them in something like a tub, with only one inch deep water, so that the ratio surface/volume is high (better oxygen supply)

Other advices and experiences will be interesting

Wow - I didn't know there were GFP axolotls. I know a little about genetics and GFP and just looked into it. I found this excellent site on inheritance of color in axolotls, with mention of GFP...but not much more, other than that it 'is inherited': gfp trait – Water Critters
I would guess that the GFP gene acts dominantly - meaning you only need one copy. If that is true, then there would be a 50:50 chance that the progeny would get it. You would likely be able to detect green fluorescence in developing larvae at later stages by use of a blacklight (long wavelength UV).

I had a good experience purchasing Daphnia online (from a company in the US). I have managed to keep the culture going. It's worth a try.

Good luck!

    And even .25 ammonia is bad what you want for nitrite and ammonia is 0 and .25 for short periods

    @DarthNyQuil, what's your ph? Ammonia is non-toxic at lower ph so might not need to panic, however if you have hard water (think calcium deposits in a tea kettle), you likely have a high pH and thus should be maintaining 0. Either way, use seachem prime to dechlorinate your water and get the added benefit of making ammonia and nitrite non-toxic for 24 hours, the peace of mind is worth it.

    @DarthNyQuil, to cycle more quickly/safely, see if you have a friend or trusted LFS with some filter media you could add to your filter. It will cycle it almost instantly, far better than bottled stuff. Speaking of bottled insta-cycle, some people swear by tetra safe start, although I've never used it myself so can't vouch for it. And finally to make it more safe, feel free to do larger water changes to get that ammonia lower- 90% of the bacteria you're growing is in the filter, 9% on surfaces, and maybe 1%> in the water column. So even a
    100% water change won't really effect the cycle process

    hey thank you all so much for your help!! i shouldn't have been so careless, but I love my axie very much and her behaviour has improved as I have started a tank cycle and gotten some good food for her

    @lvlyvoa, good to hear, np. They love nightcrawlers and worms if you have access to them, they're the healthiest thing they can eat since they're a complete prey

    My axolotls were doing fine until the cycle int heir tank crashed. I currently have them tubbed and they wont stop shedding their slime coat, and my golden albino looks a little red, and his gills dont look too good. Theyre both flaoting and im keeping the tub at 18 degrees celsius and doing 100% water changes everyday, any help on anythingelse? can anyone help?

  • AkemiYousei:
    @Jaeger I would try to double up on Prime to combat the slime coat shed when doing the 100% water changes. Also, if it's bad, might want to consider a tea bath as a preventive measure.

    @AkemiYousei thanks so much. Will do. I have also given them a tea bath before, seems to work their gills are looking so much healthier, my golden albino is swimming around frantically trying to jump out, should i be worried? my wild type is fine

    Might be the stress, or the shedding bothering it

    Make sure s/he can't jump out, and maybe keep her in a undisturbed, darkened place for a bit. See if that calms the goldie.
