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.
