LR Critter Question

[trebor126]

I have a piece of LR that always has a little mound of a very white powder on it. I have vacuumed it up, but by the next day it is there again. Looks like something is digging into the rock.. Any ideas what it might be? I have checked the web, with no success....
Thank you,
Rob

It’s probably a worm of some sort, just digging. Nothing to worry about.

it could be anything there are a lot of things that dig in the lr. maby after you turn the lights out take a flashlight and put a piece of that red renylds plastice wrap over it and go spotlighting in the tank. chances are you just might see what is digging most things will only come out at night.
