A Worm Problem?
I bought some rocks (approx. 5lbs.) that were in a display tank at the fish store. When I got it home and in my 29gal. sw tank, i later noticed that every time I fed the fish their flake food or fed the anemones their brime shrimp these worms that are half pale pink and half dark purple almost black would start coming out of every hole in this rock. They have hundreds of tiny white/clear legs like a centipede, they're not very quick, and some of them are long. I've seen some come out of their hole 5-6 inches and who knows how much of their body is still in the hole. Anyway, I have now discovered them in almost all of my big rocks and one rock must have at least 20-25 worms in it. Are these bad? Also I have anemones on these rocks. Can they hurt my anemones? If they are bad, is there anything I can buy to get rid of them?
