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? ) p3 J" D1 U" k5 J% [* }Thank you very much. 2 _' T# m0 ^9 M& \. p5 X " V1 b$ Y! }3 F! I% SXiaoxiao
