Female lays hundreds of eggs on the underside of the plant’s leaf. Male takes care for the roe, so you should remove the female. The eggs hatch after 2 days. The fry starts to swim and feed 4 days later. You should remove male too in that point. The fry grows fast but unevenly. The bigger fry can eat the smaller fry.
