I've made a water change this afternoon (about 1/4 of my 60gl tank). New water was from tap directly.The last change was made some 2 wks ago. I just noticed that one of my goldfish died and there one who keeps lying on the gravel. My first reaction was to remove the dead one and salt. I did not feed them today, as I would give them bloodworm tomorrow. My water temp is approx 24 Degree Cel., with no heater.
Can anyone help?
