We have a pond with what I would regard as "common or garden pond fish" including goldfish but we have never had enough courage to buy even small coy carp - they are truly magnificent fish and I have often seen them being hand fed by others. I am very jealous of you and your grandchildren and non grandchildren.
I hope the work goes well, sadly the weather forecast does not look too promising for the next few days but I hope that you can fit it all in during dry periods.
Do post a picture once it's all finished and those beautiful fish are swimmining freely again.
Not coy, but the only fish emoticon that I can find....
When we began
We had koi in a small pond
We knew nothing about water quality
And sadly they died
So we went on to bigger and better
Filters, UV , air stones , deep pond and pumps that pumped the water back to the filters
And the fish grew large and thrived
And 30 years later the pond leaks
And now we are re waterproofing it at considerable expense
But those fish are alive so it’s up to us to protect them
Just as Shadow is ours to protect , cherish and love
And I’ve increased his protein , he’s eating well
There is life in the old dog yet
He will live to bite again , well just to threaten to bite
