Asian in origin, the common goldfish is a member of the Cyprindae fish family. The common goldfish is related to the many species of carp, koi and other goldfish types. The name Auratus literally means “overlaid with gold”.
The common goldfish is a great fish for beginners since it’s a very hardy breed of goldfish. It can live in water with temperatures ranging from 55-80*F (12-26*C), with a pH of 6-8, which is much like tap water. The common goldfish doesn’t require a heater and needs only minimal care if placed by itself in a well filtered 10 gallon aquarium (38 liters).
Goldfish are however social animals and would benefit from having a tank mate. You can keep two of three small goldfish (a few inches or less) in a 1o gallon tank but when they mature, you will likely need to upgrade your tank size. A goldfish that is properly cared for can live for well over five years and grow to around 12 inches long.
A small one gallon goldfish bowl (3.7 liters) is not highly recommended. When you place a goldfish in a small space like a bowl, the water gets dirty fast and make the goldfish unhealthy. Read the next post for beginners: goldfish bowl size for more info. If space is an issue, consider buying a fancy Beta fish or cold-water minnows which will do better in a small space than a goldfish would.

i had three fish,they all were just fine on day 1,on day 2 they always on the top of the tank,at the end of the day they all died.
I’m sorry to hear that one of your goldfish has died. You shouldn’t replace it though; a goldfish bowl is often only big enough for one small goldfish. Change the water often to keep your goldfish healthy and happy. There are test kits that you can always buy that test for ammonia levels. Ammonia is usually the culprit of an unhealthy goldfish. Goldfish naturally produce ammonia and the best way to remove it is to change the water.
i have two gold fish in bowl one is died another is live
With a small tank you can try getting a betta fish, minnows or some guppies. Bettas do well in small tanks because they can breathe air in addition to using their gills. You still need to change the water regularly with all of these types of fish.
ok my gold fish died today and i have a small tank what kind of fish should i buy next
one time my goldfish died…. dont take advice from me.
have a nice day;D
Hi, it’s not always that easy to get your goldfish to mate. You need optimal conditions. see this post on goldfish breeding
Lol, I think slapping him might be a bit much but he has to learn that it’s not safe to touch a goldfish. When you touch a goldfish, it can remove the protective slime coat of the goldfish. This slime coat keeps the goldfish from getting sick. I’d add a few decorations so your goldfish can hide in or behind so your brother doesn’t stress it out too much. Tell your brother he can injury of kill the goldfish if he keeps trying to grab at them. good luck with your goldfish
You can buy him some live aquatic plants or a few decorations to hide in and swim around. Goldfish also like to dig around in the gravel at the bottom of their tanks; if you don’t have any aquarium gravel, add some.
