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!

    Does anyone know if aquacare general tonic is ok for axolotls as a treatment for bacterial or fungal infection?

    Hi Lilith, you can check the medications page for a list of axolotl safe treatments. Although if the infection is mild, I would stick with fridge and salt baths!

  • faebugz:
    I believe the fridge gets to about 54°, so if you can replicate that in the tank, it might be okay. I personally would fridge just to make catching them easier, and if the infection is something in the water column at all, it will hopefully die out while they're AWOL (I'm thinking like ich for fish, not sure if axies have an equivalent)

    My three inch axolotl was having trouble pooping up to a few days ago. I wasn't feeding her as often because I was scared I would just add to her constipation. I fridged her until she pooped (twice), and then began to feed her around 6 bloodworms every other day. she's been pooping everyday now, but she's at that age where you can see through her stomach and I always see poop ready to come out but has not yet passed. I don't think she's constipated anymore, but I'm not sure and i don't want to over or underfeed her... any advice?

    @Lilith, fridging is not required for fungus treatment. Read my thread on treatment.

    Its probably not pooping because its hardly beign fed, it pooped in the fridge because the lower temp caused it to purge itself. If it stays constipated you can pm me

    Hi guys. Quick question. I have newly morphed eastern newt efts. They lost their gills but they still prefer the water. I have coconut fiber, moss, hidey holes and some food in the temporary habitat for them (waiting for the other newts to morph as well). But they still run back to the water. Is it the wrong substrate? Do they prefer something other than coconut fiber? I've been doing everything else properly (According to my research) but just wondering why they haven't ventured up. Have any ideas?

    My guess is they simply have no reason to leave. Do they still get enough food in the water? Maybe humidity is too low?

    I spray mist the place every day. And I do still feed him. One of them has finally come out. But now I have another problem. They don't look like eastern newts! I am posting pictures on a thread I've started. If you can, take a look for me and see. :)
