Question

Answer
Hi Maoruff,

There could be a number of reasons.

Inbreeding, contamination, water temperature, and many other things.

In order to give you a better answer, I would need you to give me a more detailed information regarding pond size and population, location, filtering system and average water temperature.

Keep in touch
