If by bigger you mean longer, I would suspect an asternia star. Mine eat coraline algae and have left patches of bare rock behind. Never a nice line like that tho, but it does look like a trail of a grazer.

Do they hide the rocks then as I've never a star hiding and the tanks been running for a year now?

Asteria stars are tiny whitish stars. Normally they look like they only have 3 legs (other 3 are shorter) and they only seem to come out at night.
