i know i have alot of questions and would like to thank everyone for their input..but i have another one i got live rock from my buddy and i noticed that there are little white tubes (maybe half a centimeter) that are stuck on the outside of the rock and if you look really close you can see that they have tentacles...do you think they might be little apitaisas? (they also have little tentacles at the tip of the main ones) sorry i dont have a pic i cant find my camera right now...thanks alot
