Hello! I looked at your video. Goldfish eggs that are fertile and viable are transparent. When the eggs are cloudy or white it means they are not viable. I see a lot of white eggs in your tank. However, the female goldfish tend to spawn several times in the spring so I encourage you to try your hand at raising the eggs next time and to be more prepared ahead of time. The Fancy Goldfish Book by Johnson and Hess has a very detailed chapter about how to hatch the eggs and raise the fry. The book is no longer in print but used copies can be found.
Water Hyacinth and Hornwort will be your savior. My male kirin ranchu was chasing my female blue egg phoenix tail lionhead, and they both spawned eggs onto the plants. I then moved the plants into a 10 gallon aquarium.
