Another question<newbie> Burrowing

[srkr1432]

Is it possible that there could be somthing digging holes in my Live rock from the underside mostly? the size of the hole is about the thickness of a pencil..maybe a tiny bit larger...i think I can see excravted <sp> sand and live rock under these holes.????

You could have a creature doing this, I believe smasher mantis shrimp can do this.

so is that bad?

I've never seen what you're describing, though it could be something living in an existing hole that was dug by some burrowing worm or other mollusk? I know there are things that dig holes in rocks, but they usually die off of the rock before it makes it to your tank, not to mention your tank likely could not support them as they're probably filter feeders.

mantis shrimp can be bad, but I wouldn't jump to the conclusion that you have one.

I am seeing a lot of grey "dust" under these holes and behind my live rock in the back.

mantic shrimp are bad, not can be bad. If you determine you have one I would capture it and get it out.
