now heres my question, all over the original rock i bought, the one to the left in the pictures, their are white squiggle tube looking things attached to the rock, at one end a feather looking crown comes out and when scared goes back it. colors vary from red, to pink to green. i though they were feather dusters, their are about 10 active ones of all sizes and colors, my cousin told me thye may be small Apastias(sp?) the stinging anenome that can over run a tank, does anyone have a picture of the Apastia(sp?) so i can cross referance with the growth on my rock? i tried getting a picture last night, but the camera wont zoom in close enough and stay clear
