Who is tougher?

[Silverfish]

Which whould you say will win in a war, green star polyps or staghorn acro? They are both growing very close and I can't see any damage to either one yet, I was just wondering what everyone thought.
It would not be a problem to move the acro, the star polyps is another question...
