Clownfish eating spirorbid worms?

[VB313]

Lately my clownfish has been spending a lot of time picking off the back wall only thing I’m guessing is he’s eating pods or algae maybe even the coraline algea???? Only thing eles I can gues last would be my spirorbid worm outbreak? Anyone eles ever seen this?

More than likely, picking at small invertebrates you can’t see. If it is the same spot, sometimes they clean for breeding purposes as well. Whether or not if there is a partner. They won’t eat coralline. Worms are doubtful, as well, from my experience.
