Betta HORIZONTAL stripes

[Paige Isabella Marie Long]

Hi! One of my male bettas has horizontal stripes and ONLY on his head, I´ve been googling for the past hour and haven´t found anything similar. He is a little older, I have had him for a little over a year now and he was pretty big already when I got him. Does anyone know what these could be from?

Any chance of a picture of the fish?
If the pictures are too big for the website, set the camera's resolution to its lowest setting and take some more. The lower resolution will make the images smaller and they should fit on this website. Check the pictures on your pc and find a couple that are clear and show the problem, and post them here. Make sure you turn the camera's resolution back up after you have taken the pics otherwise all your pictures will be small.
