growing about a half-inch per month, you're feeding enough.

If you have a Goldfish or Koi that is NOT growing a half-inch per month you
are either underfeeding, you are keeping them in too small facilities, or the
food is not adequate to push growth. Many fish grow one inch per month.
Even relatively slow growing Ranchu's can be pushed to one inch per month
in large facilities and fed fresh proteins.

Signs of underfeeding include: Heads wider than bodies, slightly sunken
eyes, a kink at the base of the tail, poor color, thinness, trailing white stools,
and inactivity.

bodies. Very small fish
