I liked the fish the first time I saw them, and after three months in my aquarium, I was able to record them breeding!
At around time 0m44s the egg appears on the right hand side of the video, and eventually lands into a bush of Lilaeopsis Brasiliensis. The female produces 1 egg per day, sometimes more.
The male is the yellow finned one.
