I know it is a bit out of Auckland,
but there is somewhere in the Taranaki, some very keen goldies.
So much so, that a while back,
they were wanting to start a breeding pool or a club.
Sorry I can't help any more.
how long are you going for nacreous??
I do have ponds and baths, that need stocking here,
but I too, I'm afraid, am a fair way out from the BIG SMOKE
