Urgent: How can I save my Koi?
My parents have a pond that they are going to be dredging in 3 weeks because in the summer it was overgrown by some type of aquatic weed. For years the pond has been home to 4-7 fish. My mother says they are Koi but since they are full grown at about 16 inches and they have been fine without any filtration or maintenance, I think they are probably goldfish.
It is almost the depth of winter in Maryland so i assume the fish are hybernating in the mud, mud that is going to be dredged.
So what can I do to save these fish? My parents dont seem to care and will just buy new fish, but I would much rather save the fish that we have had all these years. Please help!
