No cameras available. I discounted raccoons because there was no evidence left
On very foggy memory - I think the first clean out was in the spring, and the culprits left no evidence.
The second clean out was in the fall, and the raccoons were eating the fish beside the pond.
Perhaps raccoons with young in the den during the spring would take the fish back?
(Wild speculation on my part!)
Maybe need to buy some cheap goldfish and throw them in the pond and set up the game camera to determine the actual villains?
I don't think any amount of "detective" work can resolve this issue based on the available evidence - or lack thereof.
