Too late....from healthy fish to dead in 1 hour....first fish Ive lost thru illness.....most unusual.........any ideas what it may have been still appreciated......should I be worried of other fish ect or is it just a symptom for this type of fish thanks

What are your water quality stats?

Water is the root of most problems with fish. Either that or a heart attack

Like mentioned, sounds like water quality. Did you just do a water change or use any cleaners around the tank?
