Is this duncan normal

[Onewolf]

I have a Duncan that's basically white like that. That's the way he looked in the LFS (don't remember if it was from TSA or WWC). He had one main polyp and 4 baby polyps sprouting when I got him 6 weeks ago and now he's got 1 large polyp and 6 or 7 smaller polyps.

I also have a Duncan that is much greener with longer tentacles. It has 2 main polyps and a 'baby' polyp that is now almost as big as the large polyps.

Ow, ok! And is it mantaining or slowly changing it colors with time?
