Breeding Cory Cats

It's white opaque that are the infertile eggs, and if they go fuzzy they are fungussed. Viable eggs do have a bit of a colour, with some fish having more highly coloured eggs than others.

If they do hatch you'll need to be able to feed the babies. When there are live plants in the tank - or even plastic ones covered in algae - these do grow micro-organisms on them which newly hatched fry will eat, but just in case it is better to have some food ready. I have never grown it myself, but infusoria is the best food for newly hatched fry and you'll find out how to culture this by googling it. For older but still tiny fry microworms are ideal. A starter culture and a box of instant porridge is all you need for those. You'll find people selling starter cultures on Ebat.

With liquifry, if you put it straight in the tank it'll fall to the bottom as one big drop. The easiest way to use it is to put the drop in a tiny amount of tank water, stir, then use a pipette to place the mixture right in front of the fry.

I never had much success with pygmy cory eggs in a net, because I had honey gouramis in the same tank which sucked the eggs through the mesh 
The best way to raise fry would be in a separate tank with lots of live plants.

I dont want to bring the tone down here as I'm really happy your having such success with your fish.  Fish can 'flash' against objects though if the water contains any toxins (such as ammonia) or if they are subject to external parasites.

I'm not saying this is the case necessarily as it sound like breeding behaviour from your rasboras from what you've described, but its worth knowing 'just in case'. 

Are the Rasboras Harlequins? Harlequins will also display to each other when breeding by sticking out their fins and swimming next to each other... often with a wiggle as they do.  I dont know why but I call it "sharking" it's probably an awful description but there you go!

@ Matt i think that was mean't for me. I think they are trying to mate as they are swimming close together and doing that wiggling fins together side by side.

No toxins in the water & i think they are all in good health at the moment, but that was a good tip and something else i now know for future.

Good luck with the eggs hatching apache 

Congratulations 

How large? Pygmy cory fry are tiny when they first hatch so if yours is large it may have been in hiding a while.
When they first hatch, pygmy cory fry have stripes going across the body. Then they suddenly change almost overnight to stripes going from nose to tail like adult pygmies. Which way do the stripes on your newly found fry go?

A few years ago I had no idea my cories had bred and when I did a water change I saw all these tiny little things scuttling over the sand. They looked just like bugs so I hoovered them up. Before I threw the water away, I scooped some of them out of the bucket and through a sieve, and it was only when I looked at them through a magnifying glass that I realised what they were. I'd killed about 20 cory fry 
From then on I was very careful during water changes, and I spotted a few large fry looking the same as miniature adults over the next year or so.

 Congratulations on your fry apache   

That was a nice surprise for you congratulations 

Oh no! Hope the fry survives as I'm not sure what a premature fry looks like as mine are all tiny wrigglers apart from one large one. Las I saw it has spots
