[AquaticLife] My Oranda laid eggs
They may not have been fertilized. I wonder if this is why one of them were getting fatter… from filling up with eggs? Did she slim down now? Females will/can still scatter eggs without a male figuring out they are supposed to follow along and fertilize them.. or maybe the males aren’t even mature enough. Do you have at least one male with breeding tubercles (bumps) on their gill covers and leading ray of pectoral fins?
Read up on several Goldfish Breeding sites for more info. I’ve never found a good well written comprehensive site on breeding goldfish in aquariums. Many are written for ponds which are the best place for breeding them. Disregard the smaller tank sizes in some of these articles as they were written when so many people were still promoting 10G per goldfish as sufficient water volume.

If your Google searching finds anything more comprehensive, let me know.
