I had a leak in my garden pond and had to take the fish out and put in a new
liner. That was realy pain. I put new water in, chlorine neutralizer, and
bio start for the pond.

I put the fish back in and they seem to be alright but they have been hiding
near the pump. They only come out when there is food and that is only for a
short time.

Any ideas why they are not actively swimming. I have a combination of Koi
and regualr Goldfish.
