Hi Martin,

We will all look forward to your pic and to hearing about the fish.
It would seem unusual for the heron to take all of them.

I suspect you are right...too much fish waste with too little plant
life. The heron may have changed one part of the equation! You can
change the other.

Good luck.

Could it have been a raccoon? They are known to clean out a pond
pretty quickly
