You need a lot of things, unless you are raising goldfish in a bowl.
You need: (for a tank)
A filter
A tank (not recommended under 5 gal.)
Goldfish food
Gravel
Live or fake plants (underwater plants)
Air pump (not required)
Choice of decorations
These can be very expensive sometimes, but it will keep your goldfish living longer and happier than in a bowl
Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
It's best to buy a goldfish when you are ready for the time and money that goes in to their care.Goldfish need a lot of space, excellent filtration, and regular weekly water maintenance in addition to daily feeding.
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
No, that is only about 6 gallons; fancy goldfish need at least 15 gallons each regardless of how tiny they seem when you buy them
Get a second goldfish.
from eBay write goldfish alive and you will see them but they are no that excpensive :)
That you need a new goldfish
No, goldfish are freshwater fish. Any goldfish you buy in the store are tank bred and not wild caught.
£1.29 for ordinary Goldfish and £2.99 for any Oranda
Goldfish are mostly the same wherever you buy them.
You can buy Goldfish Curry sauce in Sainsburys, and Tesco's.
there are three basic breeds: fantail goldfish, comet goldfish, and common goldfish. if you are getting goldfish for the first time, i would recommend common goldfish as they need the least care.
