Goldfish Facts

Fishbowls are no-nos
Don't believe me? If you've ever had a goldfish in a fishbowl, ask yourself how long they lived before they died - 3 months tops? Now compare this to an average lifespan of 10+ years. The Guinness Book of World Records cites a goldfish named Tish who lived for 43 years after being won at a fair in England in 1956! mmm.. makes you think doesn't it.
Goldfish need oxygen! Without an airpump or surface movement this will not be possible in a fishbowl.
Goldfish are extremely messy, poop turns into ammonia which is very toxic to them, which in turn turns into nitrite, just as toxic.
Basically, your fish dies swimming around in its own waste, nice!

Give me space
Goldfish can get pretty big, they need space and lots of it. Atleast 37 litres (10 gallons) per fish or the water volume to fish ratio must be about 1cm fish per 1.5 litres of water.

Give me variety!
Goldfish are omnivours they need varied food. Pellets, shrimp, bloodworms, veggies are all good. Peas, oranges, kiwi, cucumber are all examples that can be fed to them.

Don't use a net
A net can damage or even rip-off scales, fins or eyes. Use a plastic container or shallow bowl instead to gently lift the fish from water. You can also use your hands, but be sure to wash it thoroughly with warm water and make sure no soap remains!
