Will rust harm my goldfish....
Iron oxide (rust) is chemically inert so unlikely to have any effect although I have no direct experience of having rust in fish ponds. Hope that gives you some reassurance Tetley.

I know other metals are really bad, particularly copper. To be safe, you could remove it, let it dry and then paint it with a pond-safe paint such as P1:

Painting it black will also make it virtually invisible when it is under the surface.
