Welcome aboardIs it safe to keep gold fish together with Koi Fish?
I have the opposite in my pond, I have a group 12 orfe in with my koi. Also goldfish grass carp and tench, they all mix very well. Orfe are river fish and need lots of space and current also need a group.Just don't put orfe with koi, they are too skittish and make koi nervous feeders.
