You are getting overrun. I had that problem with goldfish for a few years until the fish got big enough to eat all the eggs and young.Well, I added about 15 guppies to the tank. I cant figure out if I have too many male/female ratio in there. Colorful girls and fast fish make it near impossible for me.
They need that morning after pill. After I took them from an overcrowded tank about 30 babies came out of hiding !![]()
