Fish eggs

I have Rainbow eggs, if they are clear/transparent, does that mean they are unfertilized?
How can I tell if they are?

From my experience with eggs , good eggs will be almost clear with a hint of yellow bad eggs will be white after a couple of days look. Closely at the eggs and you may see tint black dots in the eggs , that’s your fry , and congrats to your eggs

Rainbowfish eggs start out clear and after a few days you start to see small black embryos developing inside them. Depending on the species of rainbowfish, the eggs will take anywhere between 4 & 14 days to hatch (temperature dependant). Most rainbowfish eggs take about 6-7 days to hatch at 26C, Pseudomugils take a bit longer.

Okay, I was just looking at images of @mbsqw1d cory eggs and they look yellowish fairly quick. So I was wondering if it was the same. I've been finding clear eggs and moving them but they are still clear so I thought maybe I took them out too soon. I'm not intentionally breeding but I do have one fry that us looking good, and 3 or four eggs now moved over into a different tank
A week or so ago I moved some plants and found three tiny tiny fry which I put into a breeder box but they got out of the side slots and disappeared, probably into the filter or just tossed about.
I am trying to decide how to proceed. I could let them ride it out in the main tank...which works as I did find the three tiny fry. Also I have a empty 6g with the breeder with the eggs and 1 fry. The bigger fry is okay to be moved now, so I want to also try transferring groups over to that tank and see if they will spawn in there.
I have Pseudomugil furcatus, seriously fish says 17 - 22 days to hatch.
So just trying to explore my options.
It's late, hopefully this makes sense!

I know with corydoras, the eggs are pre-fertilised, so I could remove them straight away. Whereas rainbowfish males are to fertilise the eggs after theyve been laid? Cory eggs stay white for about 24 hours and then turn beige if they're fertilised.

Thanks. So they dont share the same characteristics. Cory eggs start white, 24 hours later, orange.
Thanks, I didn't know and thought my eggs weren't fertilized because they are still clear.
The white eggs I see are fungused. At least I know that.

Pre- fertilized, interesting. Like betta.

Thanks, so looking for embryos, not a color change. So if I see embryos then the next step is to hope they hatch!!!

This is one of them getting.. erm, squeezed

Okay, NOT like betta.

I am uncharacteristically speechless.
