Hammertime-Whats going on with this hammer?

The way it looked on March 4th (at least that's when this before photo was taken) and the others now. Plus a view of the other hammers & frogspawn, torch etc.
It doesn't have any brown goop nor anything attached to the skeleton. I have dipped with Coral RX & Seachem Reef Dip--not at the same time. No pests came out or off.

your other corals look great, so no systemic issues that you need to worry about. is there a pest nearby? placement issues, fish nipping? don't worry too much unless its a $250 torch, continue to focus on big picture here.

Thanks! No nipping fish-haven't seen any neighbors bothering it. It is an over $100 coral. So its the most expensive thing in my tank.
