Hello,

I have the JBL Artemio set for hatching brine shrimp and I have the eggs mixed with the food. I have followed the instructions but I cannot seem to get them to hatch.

I have left them for 24-48 hours at a temperature of 20-25 degrees but they don't seem to be hatching.

Is there any advise you can give me on how I can get them to hatch?

Thank you.

The main problem I had when first hatching was salinity. Once your temperature, aeration and salinity are right, they'll usually hatch. I didn't get a kit, I just made mine from bottles so I'm no expert, but I always had a high hatch rate with even mediocre eggs.

My temperature was 26 and I actually bought my eggs and salt already measured from Ebay. I got bored of measuring salt and eggs and liked the convenience of being able to take what I needed out of the fridge when I needed it with no effort. Yeah, I'm lazy with the little things.

Hope that helped :)

I never worried about temperature. I just hatched in sunlight with 2 tablespoons of salt and a pinch of baking soda to a half gallon of water. I even had good hatch rate with no salt just baking soda, the bbs take longer to hatch in freshwater. They last longer in salt water and bett hatch rate. I used air pump and soda bottle for best hatch rate. I had no luck without baking soda. I even hatched with no air pump in a 3" deep by 5" wide clear plastic container by window.

Cliff has a good point. If you live in an area with PH below 7, you need to raise it a bit or they won't hatch well, that's what the baking soda is for (I've heard around 2 level teaspoons per litre, but maybe Cliff can clarify on that one) . When I measured my salt I used 1.5 to 2 level tablespoons (those measuring spoons that you use for baking) per litre of water and per 1/2 a level teaspoon of eggs. The only reason I heated my water is because in the south east, my flat gets to about 5 C in the winter (the call to arms for socks!) so they weren't hatching at all. I stuck my home made hatcheries in a bucket of water so the tops of the hatcheries were above the water (the necks of the hatcheries bottles were held in place by suction cups with clips on that you use for heaters), then I heated the bucket with a small aquarium heater.

The initial batch I bought never hatched no matter how many batches I did, but the new ones I got all hatched under the exact same conditions. Sometimes it can depend on how the seller stores them as to whether they hatch at all. You should keep dry unhatched eggs in an airtight container in the fridge when in use.

If they're floating when you put them in, you should stir the water a bit and use a clean finger to gently wipe any down from the sides. They won't hatch if they're not underneath the water! Though the hatched shells will float too, so after about 8 hours you may see some of those start to appear at the top that don't need to be stirred around.

Thank you both for replying!

I'm going to try what you both have said and try varying it to see if it works.

Thank you!

    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.

  • faebugz:
    @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?

    @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.
