white patch on the fish body

[skoda]

i wake up today and found that there is a small white patch on the fish body, no cottony tuft, looks like is the scale and the colour also slightly darker.

i switch on my heater at 30oC and switch off last night before i went to bed (the temperature is about 28oc w/o heater on). i suspect that the fish is burned by the heater! could this be the case or could it be any diseases? this is the first time i on my heater.

please help!

I can't tell from your picture, but discus have been burned by heaters before

It could be the start of body rot.

At the moment one of my fish is the same.

One discus has a serious Bacterial infection and another has this area on his scales where it is lighter and looks strange (like you describe). I'll try to post a picture later.

The last fish I had with this was a tiger barb, over a few days it just ended up with a hole in its body and died. Hope this isn't the case (for both of us)
