interbreeding

[oranda man]

:goldfish: :fish: can a oranda and black moor breed because my oranda has been following my black moor around and my oranda is fat i mean really fat

Since all goldfish are the same species - Carassius auratus, they can of course breed.

Isn't this the tank that was already determined to be way too small for even one goldfish? You obviously do not want them breeding.

[oranda man]

i dont want them to breed but i still want to know if they could
i normally give the mountain minnows that i breed back to the pet shop

Goldfish are goldfish are goldfish.
It's not interbreeding, just plain old breeding.

But don't do it unless you have LOTS of space for fry. They get big, fast - faster than you can safely sell or give them away.
