Koi being chased

[Foley101]

In my pond i have 2 goldfish, 1 ghost koi and 2 koi, I added the koi yesterday, but the larger of the koi, are being chased around by the goldfish and other koi, to the extent that the koi floats on the surface. I am worried they might be tying to breed and I might have cross bred goldfish koi "shudder".
Any tips like should i remove the goldfish?

Give them some time, they will all be one happy family soon.
If you are worried about cross breeding, why did you put the Koi in with goldfish? I would find a home for the goldfish.

Thanks for your reply, I was manly worried for the koi's health as it was spending alot of time at the surface, although it seems to have stoped now as I havent seen the koi on the surface for a while now.

If the koi is constantly sucking at the surface of the water then you more than likely don't have enough oxygen in the pond. If it's stopped for now you might be ok.

They may have been establishing territory with the new adds, my ciclids did that all the time.
