Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
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
No, goldfish are freshwater fish. Any goldfish you buy in the store are tank bred and not wild caught.
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.
Yes they will, to prevent this you could buy a fish tank cage.
Goldfish are relatively easy to care for. The most important thing with them is to buy them clean pure water or let their water sit out for at day prior to adding it to the bowl. Purchasing vitamins for gold fish and adding filters and a heater to the tank will help.
No, it means that there is not enough oxygen. Buy an air pump.
Stores will probably sell one to you no matter what your age, but remember that if you buy one fancy goldfish (they are the round fat ones) you will need a tank that is 20 gallons (75 litres) for that one fish.If you would like to buy a fish that only needs a small tank, you can get a betta and a 2.5 gallon tank (10 litres)
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
Check with your local Pet shop they may be able to order one for you.
Pet stores have fish food. Buy some of that. Probably the best place is in their tank . Don't try taking them for a walk. Goldfish are rubbish at walking
One goldfish requires at minimum 20 gallons on it's own plus 10 gallons for each additional goldfish (30 gallons for 2 goldfish). It's not only because of how big they can grow, but because they are very messy fish & produce a high amount of waste
You can pick them up at about any pet store that sells goldfish. We have a white one we picked up at Wal-Mart and a black one from Petco.
