asterina stars eating purple coraline

My live rock is full of purple coraline. I have a red-legged hermit thats shell is also covered in the purple coraline. I have noticed that some of the purple is going away and figured it was possibly due to the fact the tank is only 4 weeks old. That was until I saw an asterina star hitching a ride on the back of the hermit, and about 30% of the purple on his shell is gone. Does this starfish think he is Mike Jones or Paul Wall sipping on some purple drink (if your under 30 you'll get that last comment, if not dont worry your not missing much)? Do they normally eat the coraline like this? I have seen as many as 8 of these starfish and enjoy the coraline much more than the stars.post-19001-1142558642_thumb.jpg

I imported asterina starfish into my last nano tank from a piece of coral I bought.

The tank was started with several varities of live rock, purple encrusted from Fiji, green & maroon encrusted from the Marshal Islands, pink encrusted from the Caribbean and blue encrusted from Tonga.

The stars starting eating all the coralline, except the pink and purple coraline. You could see clean spots on the rock around every star. After all the coraline was gone that the stars liked, they just disappeared.
