"...in perfect isolation, here behind my wall."
I have had a Green Horn Coral (at least I think that is what it is) for several months. It has shown good growth and color. This picture is under the moonlights but they daytime coloring isn't much different. There is a small section that appears to be melting off. Is this normal reproduction behavior (I assume not but I could hope) or should I be looking at other issues (water quality, pests, etc.) The rest of the tank, which is a mixture of SPS, LPS, and soft corals, are doing fine.
