You see so many coral/nem warfare posts I have to throw this up. My carpet has gotten quite large (dinner plate or so) and given the place he took footing he lays against a large candycane, a large ORA Bird of Paradise, a large ORA Spongades, and a 9" Deresa clam. I can move the clam and within days he scoots around until he tucks up against the carpet nem again. The candycane has actually grown more heads where it contacts the nem, and both the SPS have had normal growth and polyp extension. The clam's mantle touches the nem ALL the time and nothing. I've expected the worst, but nada.....everybody is happy. Just another weird aspect in my tank (tangs and wrasses also get along that should have killed each other a year ago). You see so many "My nem just killed my corals" that I had to throw this out. Now granted I have had BTA's kill stuff before, but for some reason this carpet doesn't seem to hurt anybody....and he's rediculously sticky.
