that was a horrid expierence. I don't know if the frags will get done. i tryed to do it. I have a dremmel it was too small for the rotozip head so I tryed a skinny drill bit. I pierced the coral and flesh and slime got sucked into it. i tryed to continue the drill bit didn't move smoothly and more slime or flesh was destryed. I pannicked and put the coral back in the tank. I want to look at the damage tomorrow. To see if it waas slime or actualy as distructive as it seemed. I can't really aford to keep the whole thing but i might have to. I don't want to kill the coral. Whoa.
