Help! Fin is curled with like a ball on it

[Nguyen]

My dad and I have no idea why our Arowana's fin had become like this. We looked up online and its possible that it is a rot fin, however it looks like it has an air bubble on its fin. However it isn't. Help, what is this? How can we cure this?

I'm not sure but I'm suspecting Hole In The Head or HITH disease. Can you take a clearer shot of the top of the Arowana's head?

She's running around like she is really healthy. My dad said that the top of her head looks pretty normal. Just that one fin is the particular problem. >< We assumed that she may had burned herself with the heater in the tank, but it has a protection gear around it so that she won't touch the heater itself. We were told that if we were to raise the temperature, it would help cure it, so far it seems to be working, but her fin still has the same appearance.

In that case I can't help you much. It could be a nutrient deficiency though.
