Hammer not happy?

[austenreefer]

Iv had this hammer for a few months and lately it hasn’t been as happy. All my other corals are doing well. Are there specific things that tick off hammers?

Hard to tell from the photo but my hammers don’t like mushrooms or palythos, if that’s what I see in the picture. They also don’t like high flow or too much light. Moderation in all things has given me a lot of success with this coral.
