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? 7 m' D7 z' b% C1 [- OThank you very much. 9 M: c! w# a. ~' D! j& V$ U+ u% U : R% ^! Q, ]. r" X- MXiaoxiao
