Red Spot

[Biulu]

I noticed this morning that my albino cory has a red spot on the middle of its head. He is as active as ever, and the spot doesn't seem to bother him. Does anybody know what this could be? Should I treat him for something or is it just a colouring now he is getting mature?

Anybody that can help me? Thanks to Discusangel I now know that the red spot is located at the nape of the cory!

Can you post a picture and maybe your water stats and tank info? That would be helpful.

Trying to take a pic, but he is so fast! It looks like the redspot is under the skin though, as if he had bumped his head on a heavy thing, and bruised it.
