Torch coral gone overnight

[Cosmoman44]

One of my torch corals retracted a bit yesterday and then overnight half of the head is gone down to the skeleton and the other half just shows the tips. Thought it might be my emerald crab or 6 line wrasse any ideas. It is next to a NY Nicks long tentacle torch and they have been touching but without issues for weeks. Any idea?

It's going to be very hard to say with any certainty honestly. I think it would be uncommon for the Knicks to sting it, but certainly not out of the question.

Right now I'd move it farther away, or move the knicks, to try and let it heal and recover.

You could try to give it a medicated dip, its possible its from some sort of bacterial infection.

Torches do this sometimes. They are quite susceptible to Brown Jelly Disease. An anti bacterial dip can help
