Raised white betta scale

Bubbl3s said:

Hi everyone,
I've had my betta for a few days now and ever since I bought him he has had a white, raised scale.
It doesn't look fungal or infected or like it's an injury.
He is housed in a 10 gallon tank with 6 neon tetras.
He is active, eating well and there has been no aggression towards the tetras.

Water parameters are:
Ammonia- 0ppm
Nitrite- 0ppm
Nitrate- 10ppm
Ph- 7.0

Any advice greatly appreciated.
Sorry for the rubbish photos

If he has the marble gene (I think that's what it's called), he will continue to change colors throughout his life. Or it could be a scale that got pulled loose by something in the tank.
