Alveopora feeding

[Swip]

Has anyone ever seen an Alveopora eat something?
With Gonioporas you can see them actually swallowing the food if you feed them, Alveoporas just do nothing at all.
The polyps retract sometimes but it's not clear to me if that is because of them feeding or just because the food touches them.

What have you tried feeding with? I haven't found a thing in my tank that doesn't like reef roids.

reef roids, rotifers, fauna marin seafan food, fauna marin zoa and ric food, with mortar and pestle grinded fauna marin lps grow and color and calanus powder.
No real feeding response to all of that.

Hmmm, maybe they only feed on "pico" plankton and bacteria:

Plankton uptake is usually not visible macroscopically, however particles in the pico- and nanoplankton ranges (2 - 20 μm), such as bacteria and small protozoa, may be taken up by beating cilia and flagella located on and inside the polyps.
