A few days ago I got this Green Tip Branching Hammer and it is currently in a Coral/Invert QT with 6 other coral and some snails/crabs. After dipping it he opened up nicely (see photo). Yesterday afternoon (a couple of days later) I noticed a portion of his head was retracting. Upon closer inspection it appears that there are some brown areas at the skeleton/tentacle interface. I have several photos below. This morning he is still in a half retracted state.
Is this brown jelly? If so what recommendations would you have for possible treatment.
