I'm raising a small amount of eggs right now. Each egg is in its own tub. They were purchased from a responsible breeder with known hets. All eggs were gotten locally, no shipping involved. All eggs beaned and developed well so far. They are about 15 days old now. All are still alive, moving, and I can see their hearts beating. None have hatched.

I was getting concerned as my water temp isn't exactly low (about 65-67 for the eggs) and none had hatched yet, but I can see their tail tips sort of bent as if they're too large for the eggs. A few websites I'd read through + my breeder said that once you clearly see the eyes and organs, they're about a day or so away from hatching. I've seen the eyes and organs for about 5 days now.

I tested everything in their water, and to my surprise and despair their ammonia had a HUGE spike. I have no clue how this could have happened, my breeder led me to believe eggs didn't require daily water changing until they were hatched. One egg per glass tub, no ammonia in the tap water. Their water was last changed 5 days ago.

Parameters: 6 gh 4 kh 7.4 ph 2.0+ ammonia 0 nitrite 0 nitrate

I'm terrified this is going to kill them or hinder their development, I didn't even know ammonia spikes happened unless an egg passed, which none of them have/: it was every single tub ( 5 ) as well. I put them into fresh clean water with the same gh and kh, ph was closer to 7.0 and temp was closer to 63F but I just wanted them out of the ammonia ASAP.

What are the odds I've killed them with this? Do eggs require daily changes? I'm going to start at least testing them daily, and changing if I see anything off. Will this stress them to death? Should I help them hatch because they haven't yet? Could the ammonia be preventing them from hatching? I was so excited to raise my first clutch and I feel like I've screwed it all up ): I feel just awful.

Nothing weird with your babies if they all are like the ones on the photos.
At this point, a complete water change usually triggers hatching.

As for the "ammonia spike" :
- perhaps it happens frequently but very few people check ammonia for eggs,
- even if embryos don't actually eat external food, they do process their yolk and produce ammonia and other waste. You don't precise what water volume is available for each egg,
- at pH 7,4, ammonia is mainly in ammonium form, not very toxic. If you tested total ammonia, a value of 2 isn't alarming.

So, make a water change and wait, but don't worry too much

    @Jokerjay, as in water dogs do you mean axolotls? i suggest very heavy research and a fully cycled tank before even considering purchasing one

    i highly recommend “buyanaxolotl.com”- ive purchased from them and received a beautiful animal for relatively cheap, in great condition, and excellent shipping precautions. the breeders are a couple living in georgia (i believe, don’t quite remember) and they’re fantastic. sometimes their website contact page doesn’t work, so i’d probably try just emailing them. good luck and happy hunting!

    Hi all I'm new here I'm just looking some advise on cycle witch is currently driving me insane . So we are week 8 I'm dosing daily with 4pp of amonia and for the last week has been dropping to zero witch I no is good. But my question is my nitrites are sitting at between 0.50 and 1.0 PM and nitrates are between 10 and 20 and neither of these seem to be dropping. I have done 2 40% water changes a few days ago and no change the only thing I can think of is I didnt use the seachem stability stuff which I have now ordered but surely that shouldn't have much difference this far into cycling

  • ytz13513:
    Dropping ammonia with rising nitrate and nitrite is good. It means the nitrifying bacteria is working. You just have to remove the nitrate from the water doing water changes. The level of nitrates is high and the nitrate is also high. The nitrite will be converted to nitrate using the beneficial bacteria and you can add them using quick start or allowing them to naturally grow in the tank. The latter option will take longer. The nitrate can be used by plants, so live plants can decrease the levels, but I would do a water change to get the nitrate at a level that is lower than 5 ppm. 5ppm of nitrate is natural and a good place.
