For the last few months I had seen all these tiny legs sticking out of my live rock(which at 1st I had no idea what they were till I talked to the fish store). One night a couple weeks ago we lost power for a few hours. When I looked in the tank with a flashlight well WOW they were all out and all over the LR. Just over the last week or so I havent seen any. Did something happen to them? We did have to move the rock just a little bit cuz the new trigger fish we bought wedged himself in a hole, did this do something to them?
