The rocks were just covered with them, and I am pretty certain now they are munching on the coraline. My first hint was when they moved off the rock and there were all these little white marks.....

I just can't imagine how long it would take me to pick these things off one by one.....I can't even reach most places in the tank. Maybe a glob of gum on a stick...
