I've got a few goldfish who are doing this also. It really looks like an
inch long comet is tormenting this six inch goldfish.

I would love a spawn of fry.

If you've got enough hiding places for the eggs & fry, more goldfish you
will get. Why I stick with the fantails, less prolific and easier to catch.
