Yah got the stoopid crabs out but i believe there are more of them in there. The worm is realli quite big, i was watching it moving out the rock, it never ends. Even now after i soaked the live rock there is not sign of it. Guess it moved to another rock in the tank. I realli dont wan to take any chance letting it attack any of my fishes. Traps doesnt work for it at all. These worms are damn smart!!!!
Anyway thanks, tom you've being a great help!
