Well if the 1990s Disney classic Aladdin taught us anything "it's only illegal if you get caught"

You see them frequently in my neck of the woods (UK) often in the sumps. Usually 12"+ but safe to say there'll be a few closing in on 2ft if you visit a few shops. I year or so ago there was six or seven piled up in one of the koi vats at a Maidenhead near me all above 2ft with one far larger albeit not a marble.

The regular ones get quite large indeed. They are invasive here, and i have seen them grow up to 2.5 feet in the wild. But like you, i have never seen a wild marbled one.
