As i said in your last thread you should not have put the pair back together for at least 3 weeks to give the female time to recover, once they start Morgurnda species will continually spawn if males and females are kept together. In the wild the temperature in their habbitat drops significantly in the winter and rises in the summer, but in a tropical fish tank where the temperature is constant it is like summer all year round, which is breeding season. For the good of your fish you must either seperate them or keep the temperature below 21c, but do not drop the temperature if other tropical fish are present.
