yes, they should get on great, but watch them to make sure that the slower fancy goldfish get their share of food. also watch them in breeding season - if the other goldfish are males, they may chase the fancies too much and exhaust them.
Hi thats great, thanks for the info. The thing is my Bendy (Ranchu) is actually quite fast. And he always gets his share as he is the biggest fish I was wondering when is breeding season? And do you know how to tell if they are Male or Female Ranchus? and goldfish?
