I bought a small 1" Favites frag a couple of weeks ago. I had the perfect spot for it, about 2" away from a 8" Sarcophyton I've had for years. I was worried the Favites might suffer from some toxins of the leather, but it was upstream so I figured it was worth a shot.
The day after I added the Favites, the Toadstool closed up. Just shedding, I thought. A week and a half later, no change, and the Toadstool was now 3-4" away from the Favites. So last night I moved the frag to another location. Tonight the Toadstool is sloughing off and the polyps are popping out. Coincidence, maybe, but I'll keep it in mind when placing corals in the future.
