Illness or burn?

[OzShrimp]

Meet Jack my daughters new betta we brought her yesterday. When we got him he didnt have the white mark on his forehead yet this morning it has appeared.

Not sure if it is some form of illness or a burn from the heater in the tank. Hopefully someone can advise me ?

Looks like an injury, where it might have got it's head trapped/wedged in something and lost it's scales trying to escape.

A half dose of melafix or malachite green to prevent infection might be a good idea.

Thanks for the input @jayc

My SF/s use to like hanging around and behind the heater, lucky no burns though. If you haven't already got floating plants in the tank place some vegetation in a corner away from the heater and he should, should hang in that corner preferably to the back of the tank.
