I have two heads on my torch that have just disappeared. No brown jelly...no anything. Before I went out of town last week I noticed one had packed up and moved out. We came back from a 4 day vacation to find another head completely bare.

No parameters are out of whack and my other corals are doing fine. I have a maroon clown, lawnmower blenny, neon dottyback and mandarin. Also have a conch, serpent star and a few blue-legged hermits (which I have my eye on).

Any ideas? I have had corals die before but never just up and disappear.
