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? / ?, t4 `+ Z0 f5 D" C7 mThank you very much. 0 G7 z( i2 `: i% f 5 b9 ^" Z4 S+ I4 g( hXiaoxiao
