Markings on Tailspot Blenny

[austin_socal]

Hi everyone,
I just bought a tailspot blenny and was wondering if these markings on him were normal or some type of disease.
TIA

Probably just coloration when sleeping/spooked. A lot of fish desaturate or get some mottling at night to help blend in when they aren't active.
