It depands what type of fish but i know that if you have a betta fish you should change it's water every 2 weeks cause if you change it every week then the betta fish will get stressed and when betta fish get stressed they die. Well i hope this anwers your question.

Betta fish - Siamese fighter fish are not salt waters fish. But there is another breed of Betta which is called a marine betta and they are salt water fish.
Betta fish change color by there environment and the types of food that you feed it. If your Betta fish is loosing color that means that your Betta is sick.
A betta fish should not be in water colder than 72F
No, Betta fish like clean, but not sterile water like all fish.

Betta fish are fresh water fish. Most tropical fish are saltwater fish. Betta fish also only get along with a few fish.
of course you do you need the fish to have WATER because every fish in the world needs water so the betta fish needs it to,to live so the betta fish does need a FILTER
Any bigger fish, more aggressive fish, no water
