Anemone chewed on or sick?

[AlexNY]

I have a LTA that has been happy and healthy since I got her about 6months ago. Just recently I noticed that she looks sick or like something chewed on the bottom of it. I haven’t added anything new to the tank. I have emerald crabs, foxface, tomi tang, wrasse, clowns, snails. Water conditions are good. any thoughts or suggests are appreciated
