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? # u% Z9 r& Y5 L8 O1 Q5 mThank you very much.2 f# s/ f$ @8 G+ g7 W% W6 K$ X
