White spots on mangrove?

[djryan2000]

I recently bought a mangrove and put it in my tank with it being suspended from the top. After a couple days I see there are some white spots on the dark part of the plant that was underwater when I purchased it. What are these? Should I be concerned?

Edit: I felt them and they feel very bumpy and attached to the plant - they didn't just fall off.

Foraminifera maybe? Harmless filter feeders.
