difference between a normal motoro and a marbled

[rstrack]

I was woundering how you tell the difference between normal motoros and marbleds? I have seen some normals that look like they would be classified as marbles? Ronnie

Really need some pics, marbleds are marbly and normally just have spots....I expect there are variants in between though.

Marbleds are generally accepted as a smaller fish
