Common or comet goldfish in pond, how many?

[ember04]

Hi there
as you may of see from a few other threads of mine, I am starting a 140 gallon 525-litre pond with the dimensions of 150 wide, 70 deep and 50 heigh (cm)
this pond will be insulated and heated over winter
I am going to get a few common or commit goldfish (not together)
my question is how many single-tailed goldfish can you get in this size pond
It has lots of plants and a large very filter.

oh if they don't work what other options are there I am good at tropical fish but not pond fish

Go with 6. They will breed and then the population size will sort itself out.

OK do you think 6 single-tailed goldfish would be ok in a 140 gallon

So common have short tails, comments grow long tails . Other than that . They’re about the same in everything else . For that size of pond . I would put about five since each fish will grow over a foot .
