lol ok sounds good thanks allRichard said:If the piece isnt too big , what you can do is take out the frag dry off the bottom apply glue, dip frag in water to form a skin then mash the glue into the rock in you tank and hold for minute or two.
But make sure you dip the frag in a tub of tank water and not to dip it in the tank. Sometime a skin from the glue will float off and if a fish eats it it will glue its mouth shut.
