What size is your tank? Is it cycled? Koi arepond fish they get way to big for most home aquariums.

I agree koi shouldn't be kept in fish tanks they grow to big.

How many gallons is the tank.
Water stats in ammonia, nitrite, nitrate, and ph.
What type of goldfish are they.

Immediate water change and increase aeration.
