what to have in a fish tank goldfish
Keep your goldfish in a fish tank no smaller than a 10 gallon (about 38 liter), and make sure that a minimum of 6 gallons (23 liters) of the space in that fish tank is dedicated to each goldfish (each goldfish should have 6-8 gallons or more (roughly 23-30 liters or more) space in the goldfish aquarium).oldfish should never be kept in a fish bowl. Perform your weekly 10-15% water changes, so that your goldfish always has clean water and so that any waste that is not processed by the aquarium filter is removed.
