Some thing is drilling through my rocks

xtremedelta · 12/22/2006, 10:09 PM

Ok, so I got some new live rock, and I must have picked up a hitchhiker that I have never heard of, or seen for that matter. I know its in there because, what ever it is is "drilling a almost perfectly round hole about 1/4'' though my live rock, at first I thought I was crazy, but I looked at the sand below, and I saw a mound of dust from whatever made the hole. has anyone heard of this before?

Could be a mantis shrimp, check with the lights out if you have one you will need to take him out unless thats all you want to stay alive in your tank. Becarefull they pack a punch!

Yes i have a ton in my rock. I think they are little worms but i don't know the name. I got some big ones too, some are close to a foot long.

Maybe a pistol shrimp?

I had the same thing when I cooked my LR for 2 months. I never seen anything that was the cause of it, and I had the tank for a year with the rock in it. Never had any fish problems, so don't think it was a mantis, and never heard the click that they make. So whatever it was, I don't think it was a mantis.

could be a rock boring oyster or clam. they dig effieciently into rock but not fast as far as i know. just another thought. i have seen the oysters as they are small but this sounds more drastic. post a picture then youll get a better answer.

Could also be a rock boring urchin, but you would probably have seen it.
