what you could have is a foraminiferin <a href="http://www.reefs.org/hhfaq/img/Foramr.jpg" target="_blank">fmf</a> there are a couple different types but this kind is sand size. they seem to appear in groups then dissapear they die off and fall into the sand. then they show up again. my scooter will climb the glass and eat these things up and if i clean them off of the glass the other fish grab em. just harmless filter feeders thats all.

Six line wrasses eat pods for that matter most wrasses eat pods, What am I thinking most small reef fish eat pods as well as most reef shrimp. I guess at the top of my list would be a Six Line Wrasse or Coral Banded Shrimp.

My lunar wrass eats pods but they are harmless
