Bummer!
I have a quick question though. Are you on city water?
I think I know what you may be getting at...if what you mean is ( especially this time of year) more chemicals which are harmful to aquarium fish are added to city water supplies....for what its worth...I am in an upstate NY suburb and to my knowledge all my area water is a county supply...i have seen a breakdowm in the past of whats in there but have not looked at it in a while....either way the female jag in the same tank has shown no sign of illness.....thanks for seeking an idea for possible cause.....
