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? 2 i" v6 A" J3 t6 bThank you very much. R4 z) Q4 \: m4 w4 a( r 0 {7 K+ K* P" A5 w, r* ~9 ~Xiaoxiao
