Yes.  GSP's were my first Frankenstein ten years ago.  Superglue gel works wonders.  GSP can be very invasive, so if you think you might not want an entire tank of it (or half a tank as was the case with mine back in the day), you might want to separate it from other things on an island or a set of rocks that can removed for fragging in the future if needed (not trying to scare you, but somethign to think about).
