Puzzled over low hatching rate!

[MadMatt]

agreed, and I changed it because I am sure that is what he meant. John, if not, please change it back.

I assumed he meant 82degrees, and that's what I am at 82-83 degrees.
It's a total puzzling event, the time frame is all off and I agree, as I stated before the wigglers seem to just freeze in the wiggle and croak, I was looking at the eggs now from that picture I posted, most of them seem to die in the egg shell.
Has anyone ever experience this?

I would possibly try to lower the tds to 50 and see if that helps.

Yes I agree, John suggested 20% tap water, 80% RO, this will lower it to around 40-50 TDS, let's see what happens.
Thanks!

IMO 30% daily is not enough in a breeder tank. All mine get 90%+ and a good tank wipe down each day, until I have eggs, then I scale it back to 50%.

Since you have multiple pairs having the same issue take one pair and eliminate the flakes from their diet for a couple of months. Feed only high protein foods. The increase in protein will increase the vitality of the eggs and embryos. Might help and certainly worth a try.

Yea I meant 82..what did my blind *** type?

[Keith Perkins]

You fat fingered one key to the right...92.

[John_Nicholson]

Yep at that temp the males fertility rate would have been really low......I am turning 50 in December and probably need to start wearing reading glasses when I type....LOL.

Hi John, thanks for the info.
BTW: what percentage do you change per day?

[John_Nicholson]

50% daily.

-john

[MadMatt]

50% daily.

Maybe I should raise my wc as well.

My suggestion is to change one thing at a time If you do several things at a time you won't be able to tell where the problem lies. This is not a life and death thing so take your time and do it right. Fisrt uncage the eggs with the parents are not confirmed egg eaters or cage the eggs and add an air stone and dribble meth blue over the eggs. If that doesn't work, use more RO and less tap. I think that 30% daily is fine for a pair in a 29, but more never hurts.

I see this happen many times with some hobbyist, and end up with their pairs after they have no success. Sometime it would be a case of thining out the eggs.

Hi Cliff and thanks for the input.
What do you mean "thinning out the eggs"?

This is a solution that some breeders use that can thin the shell helping hatching. This solution does put an edge on the hatching but the problem may be that
the batch is just too weak, this mean the fry will start dieing off anyway.
