Your question does not give enough details for anyone to be able to give you a good answer. How often do you clean out your pond, filter, pump, skimmer, etc...? How often and what do you feed your fish? Are there any predators in your area like herons, racoons, cats? There is a good web sight called www.wetwebmedia.com that can answer just about any fish question you have. Just look in the right category for pond fish health and browse through their pages. I'm sure you will find your answer there. Good luck with your fish.
