White Growth on Anemone foot Picts, Help me out..

[Ryanhdd]

Hey guys and girls I need some help with the Rose BTA that I got about a week ago. Its been doing fine up until now. IT is not really eating and has a white growth on the foot. Kinda like something is eating at it. But i am not sure. It has not opened for at least a day.

Any help would be great. Thanks
