To keep a Goldfish successfully you should follow the basic rules of fishkeeping. Those rules are :- 1 inch of fish needs at least 1 gallon of water (a single Goldfish needs at least10 gallons of water). :- Every fishtank needs a permanently running cycled filter. Every tank needs at least 50% of its water replaced every week.. A Goldfish likes a pH of around 7 to 7.2 and a temperature of around 55F to 65F. They should be fed as much as they can eat in 15 minutes every morning and evening. Provided the water does not feeze solid they do better in outdoor ponds than they do in indoor aquaria.
the one which is suitable for ppl's living.
If the goldfish is swimming in water, it is alive.

Yes. It should be fine. I have 2 regular goldfish living with a bubble eye goldfish and to fancy fantail goldfish, so I think it will be okay.
Goldfish do not populate any rivers. This because goldfish are not wild animals, so for one to be living in a river would be about the equivalent of a golden retriever living in the woods. Goldfish do not populate rivers, however, they can be commonly found in outdoor ponds.
There are many aspects that give communal living locations their prestige. The best provider for communal living is Intentional Community, which creates a friendly, pro-social environment.
Despite common mythology, Goldfish have a memory span in excess of 3 months and can distinguish between shapes an colour. Some goldfish are even able to learn tricks. As the fulfillment of a fish's dreams are not communicable to humans, there is no point questioning whether a fish is feeling depressed. However, if you do find yourself asking the question, then interpret it as a reflection of guilt you may be feeling for mistreating a living creature (which was originally meant to be for your enjoyment) and make any necessary amendments to the way you look after your pet. With great power comes great responsibility!
About 20 or 30 years. It depends.
The goldfish will get more oxygen in the day, but at night, they will be competing for oxygen.
