Do they all survive?

When you have a batch of fry would you expect to raise them all successfully?
I seem to be losing a few,

I tested the water and there was some ammonia, nothing measurable but it wasn't zero.
The nitrite was zero and the nitrate was an acceptable 5ppm
The test kits aren't new so i wasn't expecting great accuracy.
I cleaned the filter and did a partial water change just in case.
I will test again tomorrow, and the normal water change is due tomorrow afternoon anyway.


There was a noticeable reduction in the number of fry overnight last night.

They were free swimming on Sunday.

I just wondered if other people would expect to keep them all alive and thriving.

It goes that way sometimes. As long as you keep up daily water changes there's not a lot you can do. As you have more spawns you'll probably find less die even though you don't do anything differently. That's my experience anyway.

I'd always expect to lose a few, but if you're losing significant numbers make sure you're not overfeeding, if they have pink bellies don't feed. If they have very fat pink bellies, you've overfed.
