How many goldfishes can you put in a 100 gallon pond?

Question

i added lilys ect.

Answer 1

Depends, size of the fish. if it's filtered and how often you change the water?

If it's just a basic tub of water, then only a couple of large comets.

If it has a good filter and you do regular partial water changes then maybe 10 fish.

Answer 2

Koi - 4

Goldfish - 12

They will get bigger and grow longer and keep in mind the oxygen they will be using so dont forget the air stones to. Also they have to turn around to.

Answer 3

NO KOI.  Koi need 250 gal per fish.  If it is properly filtered and, if nessecary, you have a tank to bring them inside, 5 comet/sarasa/comets or 10 fancies.
