Liverock getting holes in it

[m.rogers]

My liverock is starting to get holes in it is there something thar will eat rock? The onlything that i can think of is i have some snail like thing in my tank that i did not buy they are come shapped and you can see what ever it is at the larger end of the cone or the hole thing when it is on the glass.

are there any urchin's in the tank.. I have heard they will put holes in rock. I have a purple urchin that came with my lr he has not made any massive damage..
just a thought

i have some worms that eat live rock "or i guess they eat it" i have these little piles if liverock dust or maybe i have termites but i had a rock with mushrooms on it and it was solid when i first put it in my tank and a year later when i upgraded i moved them and the hole under side of the rock was eaten and there was a worm that was 9 inches long " scarry" that made its home there
