I didn't see any immediate responses and grew concerned, so I figured it was best to try to get out what I could. The fry are tiny and I have aquarium gravel in the bottom. Some of the gravel pieces are likely bigger than the fry. I think the dead ones sank into the gravel. I could only find 8 of the dead ones. The 5 living are so small I was worried I might either hurt or scoop them up retrieving the others.

I did contact my supplier and he says he will make good on it, (crossing my fingers).

I'm going to give it another day or two then maybe attempt to change out some water.
