Urgent help needed Pulsing Xenias "Dissolving" !!!

[Gus]

Hi All,

I noticed this morning that my Pulsing Xenia's and 1 Hammer Coral frag are looking a bit strange.

The parameters are all spot on. The only thing I did was to clean the underside of my lights to remove some dust ?

I have 2 sets of Xenia's 1 at the top of the tank and another on the tank floor. Both are not happy. Also, I moved a hammer coral frag on Thursday up to the top of the tank because my bi-colour blend was nipping it.

Further than that, there have been not changes in the tank. All the other corals are happy and inverts seem fine as well.

I have attached some pics.

What are your thoughts here ? Should I remove the Xenia's or will they recover ?

Thanks.

I would hazard a guess that your hammer coral has possibly sent out sweeper tentacles overnight and stung the xenia?
