Today I went out to the greenhouse and noticed these tiny gel-like balls all across the walls on the inside of the stock tank and on the faux floating lily pads.
I knew, they had to be koi eggs. My one fish had blown up; I was worried she got bloat, from which most fit don’t survive. I took a video and photos of her (via our under water camera.) She was huge and spending a lot of time on the bottom of the tank.
When she did swim. a couple of the other fish would come along and bang into her, as if to knock her off balance. After reading many articles, I discovered the fish were banging against the female to help her release the many eggs she was obviously holding.
This behavior went on for about 5-6 weeks. No eggs. I was beginning to wonder if she was unable to pass the eggs..
