Sounds like snail droppings but you didn't mention having any. You might have gotten some stomatellas with your live rock. Have you ever looked at the tank after the lights have gone out and found any?
Well I may have some...wasn't sure what a Stomatella was so I did a search and found pictures so I know what to look for...I have looked at night that's how I know of the bristleworm lol but I have moon lights now so I'll be keeping an eye out...thanks. I understand stomatellas are friendly correct?
