How to have golden fish

geogie

My friend gave me four golden fish and a big fish tank. But after two month, these four golden fish all died. I don't know why. I usually have them in the temperature about 22-25C. Feed them once a day, usually at night. I think it maybe is infected by some virus or bacteria. Because after the golden fish died, we found that their tails all are damaged. At here, I ask for some having experience why?

不用老喂。once a day 太多了。这样水容易脏，导致缺氧。
