I've had a new pond that I've put in about 2 weeks now and it's about time to put some fishes in it.

It's a 1000 litre item, 2 1/2 foot deep with a decent enough pump and filter (and uv bit).

I'm probably going to just put goldfish in it, something hardy, but I've had various suggestions.

Should I go out and buy a job lot of 10 - 12 all in one go.

or buy 5 - 6 wait a couple of weeks then add another 6.


Guessing fors and against for each.
For buying a job lot, they might not fight as much, but if one has an infection, they'll all get it.
thanks in advance
