No that fish is not mating there is something wrong with it, get it into a
separate tank and treat it if it is not dead already, unless you paid allot
for it I would just flush it, sometime it can cost more to correct it then
it is worth. I sounds like a parasite, and or bladder problems which is hard
to help sometimes.

One of my ponds has ~250 koi fry and I see this behaivor randomly/
fairly frequently amoung the group. I always guessed that they were
spooked by my presence - producing a most extreme escape maneuver (?)

I have a fish doing wild corkscrew movements around the pond and floating
