So we have a water garden in our back yard. It is about 800 gallons maybe a little bigger. For the last 3-4 weeks the comet goldfish have been spawning like crazy. Now the adults love eating the eggs so I am suspicious that they are only producing them for their eating pleasure.
Regardless, many fish are hatching and watching them grow is quite enjoyable. I had set up one of my unused 55 gallons in the house to raise some of them so that I could get a higher rate of survivors and hopefully sell them next year. These fish aren't exactly cheap.
Almost as soon as I got the tank set up they spawned again. I removed one of the plants the eggs had attached to and place them in the aquarium. Yesterday, they all started hatching. For the first day or so they don't really behave like fish or look like fish. As soon as they hatch they just find something to stick to, such as the walls, to absorb the remaining nutrients from the egg. I expect they will be free swimming today or tomorrow. Since they don't move it makes for easy counting and there is well over a hundred of them. It will be fun to see what colors they all turn out to be since there are many possible combinations due to the variety of adult colors. I will try to take a picture later, but for now here is a picture I found that is basically what mine look like right now. They just stick to the glass.
