Guarding Against Sick Fish
Fish disease and death can be very frustrating. Unfortunately,
it even causes some people to give up on fish-keeping altogether.
But a little knowledge along with some basic precautions can be
very powerful in the health of our goldfish and koi. Maintaining
good water quality is extremely important. It's also important to
make sure you are starting with healthy fish. If you purchase sick
fish, it's going to be an uphill battle at best. Buy your fish from
a dealer you trust. If you are keeping high-dollar fish then trust
is not good enough. You should set up a quarantine pond for new
fish before mixing them with your other fish.
If a health problem does arise, your first step should be to test
the water (you do this once a week anyway, right?).
