Recognising Zebra Danio Eggs

[testingtesting123]

I'm trying to breed some zebra danios for my mother in law's empty tank, and this morning I put 5 of mine in a large livebearer-type two-level breeding trap for a couple of hours around dawn.
There are now some little white specks at the bottom of it that weren't there before, but as I'm new to breeding egglayers I'm not sure if they are eggs or just bits of detritus? I've read danio eggs described as little bubble or glass-like things, but these just look more like tiny bits of dandruff to me!
I've not had much luck with an image search to compare against, so here's a close-up photo. Do these white flecks look like eggs? And if so is there any way of telling if they're fertilised or not?

Yes, they are eggs. But I wouldn't try to hatch them. Just get a gravel vac and siphon the water out that you are keeping your danios in. Empty the water into a large container and look for fry. If you have a male and female danio, I can guarantee there will be fry in that water.

Thanks for the response. I'm surprised how tiny they are! I've got a gravel vac knocking around somewhere, and a suitable bucket, but I don't have a spare heater and it can get pretty cold at night here. Is there any particular reason why you wouldn't try to hatch these eggs, though?

because the fry that you siphon out of your tank will be already hatched and probably live more than the eggs or the fry you hatch yourself. example: I had about 20 good fry in my bucket. I picked 6 and dumped the rest into the toilet. 5 of 6 of those fry are still with me. Or, if you tried to hatch the eggs, 3 of 6 probably hatch and then 2 of those 3 would only survive. So, you can see my point.

Where do you live? I don't think you'll need a heater but I need to be sure.

Makes sense if it would yield more. I live near Liverpool, room temperature in my house is about 20C during daytime and 10C at night.
Think I have an idea though, I could put the siphoned water in a plastic container floating in the community tank to keep temp at about 24C?

They don't look right to me.

Your right in when u say their like glass, and their around 1mm in length.
Their easy to breed, i just set up a new tank with a sponge filter an let it settle, move in the breeding groupe and usualy with in a couple of hours off they go!!!

The specks look to small but i may be wrong.

also i woudl of though a breeding trap would be to small and these are quite energetic fish when breeding and i like to use at least an 18x12x12 for breeding

They don't look right to me.

I kinda thought that myself, but couldn't think of any other explanation for what they could be. They still hadn't hatched this morning, a couple of them looked a bit furry so I added a drop of methylene blue. About 10 seem to have turned darker, but I couldn't see any movement. Perhaps they weren't fertilised?
The adults seemed happy enough in the breeding trap, it was only for a couple of hours. It was only a lack of marbles that made me use it.

If they have gone darker then they may be eggs.

The white ones are dead and should be removed if possible as the fungus can kill good eggs too.
if they are egss they should hatch any time soon from 24-36 hours

Just in case anyone else finds this and wonders what happened, those eggs - or whatever they were - never did hatch. Not to worry though, there are about 100 wrigglers swimming about the tank as I type
