Lyretail anthias under the weather

[mcs]

We gave one of five lyretail anthias that has been well for s year. She has been hiding the last three days. She had been the most aggressive eater in the tank, but now she comes out a short way with feeding for a short period, but does not eat
She appears well otherwise , no obvious marks.

Is there anything I can do to increase the chances that she will live?

Have you recently added anything wet to the tank?

 

[mcs]

No new fish.

New coral, macro algae, sand, rock, inverts?

 

[mcs]

New coral yes. Several new sps and chalices.

Unfortunately the coral dips only remove coral pests. Fish parasites aren't removed. So it's possible you introduced something with the corals.
