Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Parasites in my Largemouth Bass

I am NOT an expert on fish health problems.

However, opportunistic infections and opportunistic parasites certainly do better when the host is facing stress conditions.

Hopefully your problem will recede a little bit as your fish fully transition to "winter mode". (But don't take that sentence to mean you should quit fighting the little bastards!)
