Well since I have always wanted Christmas tree worms, i finally got 1 today and i love it soooo much. I was wondering if i put a BUNCH of them in my tank, if they would be ok. How much lighting do they need? what do i feed them? will my royal gramma pick on them?or my goby or my pistol shrimp? also is there anyway to move them out of there little holes so i can put them on smaller rocks?
