Hi and thanks for your reply. Yes, I have goldfish in the pond, nothing else. I'm constantly checking on the pond & looking at the fish & don't see how this one got as big as it did without me seeing it. The water is clear. But it has a rock bottom & sides & the fish would have blended in I guess. Still...
Also sorta worried about why it died. I checked the pH this afternoon & it was okay. The other fish seem fine. I've had them since right after the pond was built last May & have stopped feeding them since the water temp dropped below 50 most of the time as advised.
