Polyps

[Rmckoy]

Why do some acros have very long polyps that extend when adding zooplankton
But others are tiny ?

Some are long string that flow in the current

I just noticed rocky ( lawnmower blenny ) in the back of one picture

Those are messenterial filaments. I have never had anything good come when I see them. Other say that they see them during normal type feedings on a regular basis.

Good or bad ?

It depends whom you ask. Bad for me.

Mesenterial filaments are string-like extensions of the mesenteries—the internal folds of tissue which create structure within a coral polyp's body. They are typically bright white and full of nematocysts—specialized stinging cells that corals use to capture and kill prey, and to sting their competitors.

Doesn’t sound bad at all ....
except for what frags could be within close proximity
