We have or at least I put 99 fish in the pond this year. And we just bought two more Butterfly Koi we just for some reason had to have. So I guess all tolled we have 101, and I am looking for homes for most of them. We gave them away by the cooler full last year cause we had over 200 we wintered over from the year before... All from the 11 fish we started out with.
I really do not know how much water the pond holds. One section is 23 feet by 11 feet and is about 4 feet deep in the deepest area. there is a sort of slow flowing stream which is 2 to 3 feet wide and 1 1/2 to 2 1/2 feet deep which joins the larger section to another which is 8 feet by 12 feet and is about 32" deep.
With your husband it sounds to me like more training is required. It took me a while to get the hang of point and dig...
