I have little white hairs on my live rock

[hillegom]

How long are these white hairs and how far apart?
Do several come out of one hole or are they solitary?

Foraminiferans aka forams? This is a huge group of Protista (not animal nor plant). The ones I am thinking of come in red, pink and white and are spiky and hard. Each color is a different specie I think. They are common and expected in reef aquaria.

Foraminiferans by Ronald L. Shimek "There are similar white foraminiferan species found in aquaria. Their bodies look like small "spiky" versions of a stony coral, rather like nano-sized versions of bird's nest coral, Seriatopora hystrix. These foraminiferans have not been identified to species."

they are very close, and no sorry they are not coming out of holes, they are on my live rock. i only have one piece so far so i can easily see them all. they do move in my current though.

Move in the current? Hmmm, not forams. Is it the cilia of algae?
