I had spent a lot of my time on the internet searching for information about goldfish fry and eggs, most of the photos I found were blurry and of no help.
Here are some photos of fresh 1-day-old eggs:

These eggs are not all fertile, but you can readily find descriptions online of how to tell if they are. It appears that my filters are the perfect spot for the eggs to attach and you can tell they are tiny by comparing their size to the fibers in the filter.
Because of the continued egg laying, I rinse my filters daily. If I do not, the water will begin to smell. Another way to tell if your fish has spawned is to watch and see if the males are chasing the female, and then later, the water will be milky and have an odd smell. Rinsing the filters daily also lessens the chances of any more fry hatching. The rest of this concerns the fry that I am currently raising.
I have at least 3 Oranda males perhaps 1 juvenile Black Moor male in with a single Calico Fantailed female. I am not sure if this is what has caused the increase in spawning or not, but I do know that until I added a rather aggressive male, there were no eggs dropped in over 2 years.
Day 1




These fry hatched on the material part of the filter cartridges within my 350B bio-wheels!
I went ahead and gently rinsed the filters in some shallow water in a large PLASTIC container and made note of all the fry.
Good portions of the fry were dead, leaving about 20 that were strong swimming with straight backs.
Go ahead and cull those with obvious defects, such as detached eyes.
The fry were transferred into a 20gal Long aquarium, with already treated water (Salt/Aquasafe, ph checked), a small portion coming from the main tank to add nutrients but a small enough amount to minimize the amount of potential threats. The water is about 11” deep.
Fry like to cling onto surfaces when they are newly hatched, you might notice they will use the surface tension on the top of the water to suspend/cling along the side (photo 1 & 2).
I strongly recommend the use of live plants with fry because of minimal stress and nutrients as well as providing them places to rest. Plants will provide oxygen to the fry without the need of aeration.
As you can see from the photos, they still have large egg sacs connected which shrink as they get older.
I have not started using any sort of filtration at this time.
On day 3 I will use a small tube to remove waste and the fry that did not make it to maintain water quality.
