Right, that makes sense. I just wanted to double check, I was getting a bit harrassed when I wasn't sure how many of each I was looking at getting and this woman was sure that each variety needed their own group to shoal instead of just joining with the others.
It's for an outdoor pond, so I was mostly hoping to get a pretty mix of the hardiest of the goldfish species.
I spoke with my local goldfish/koi pond club and some of the members have offered to share sexed adults(almost all of them prefer to have single sex ponds so there is no breeding, so they sell/give away the males or females when they are big enough to tell the difference. They also suggested I have a pond of all one sex as well so that I wouldn't end up with surprise babies and overstocking the pond)
