Keep only one goldfish per 2 gallons
A cover is not needed but is
recommended, as sometimes fish will jump out.
A filter is not necessary, but
highly recommended, as it will help remove both solid and chemical
waste and keep the water looking clear.
One inch of gravel at the bottom
will provide good surface area for good bacteria to grow on. This
will help break
down some of the goldfish's waste.
Tap water should not be used on it's
own to keep fish, a water conditioner (such as Aqua Plus) must be added first to remove chemicals like chlorine and
Add a 1/2 teaspoon of aquarium salt
per gallon of water to
your bowl. This will help prevent and cure disease.
It is best, and much less stressful
to the fish, to do small water changes more frequently than large
ones once in a while. For bowls under five gallons, change 1-2 cups
of water every day, and one half of the water every week by putting half of the water and the fish in a
bucket and then stir up the gravel inside the container. Then try
and dump out as much of the debris as you can. This will help keep
your "good" bacteria in your gravel alive.
Remember to add a water conditioner
and aquarium salt to the new water before putting it back in your
bowl. The chlorine in tap water will kill your "good" bacteria.
Fish will catch disease whenever
they become too stressed. Moving from one bowl to another, not
changing water frequently, overfeeding, and adding too many fish
will cause stress.
Always have a jug of water, already
conditioned and at room temperature, available. This will make water
changes quicker and easier.
