Haha Cutting, I have these things ALL OVER MY TANK!!!!
I just had the lights off for 5 hours and approached the tank with a flashlight, and these things are EVERYWHERE. And ALL THEY DO is take this stupid little dirt tubes and pass them on to each other. I can honestly say I saw one of them pass a tube of dirt to his buddy on the bottom of the elegance coral.
They are freaky little freaks and Im scared to go to bed and have dreams about them!
