I have an outdoor pond with 7 common goldfish, a fantail, an oranda, and 2 koi. They are all about 4-5 inches. The pond is very well planted.
About a month ago I brought some plants inside to put in an aquarium and a few days later I found 4 fry. I still have them and they must be goldfish. Yesterday, I brought in a water hyacinth and now there are more fry. Unless there are flying fish around that come to my pond at night, lay eggs, and then fly away again (I highly doubt it, LOL), they must be goldfish.
I thought that they only spawned during Spring. Do goldfishfish this small even spawn? Does this make sense? What else could they possibly be?
If it would help I could take a few pics, but most fry all look alike anyways.
Sept. 1 EDIT: We have established that they are goldfish fry. I will keep taking pictures of them to show how they develop into beautiful (hopefully! lol) adult goldfish.
