Unknown dots moving about.

[Ebutler14]

Recently noticed brown little dots swarming on the glass near the sand. The urchin seemed to be dropping them from the bottom from some sort of glands. Have had the urchin for about 3 years. Corals don't seem to be affected. Sps and Lps have had steady growth for past 6 months or so. Can anyone ID these or had something similar?

Planaria or pods??

Zoomed in on them
Don't see a triangle head and some seem to have little antenna

I'm pretty sure that the first pic in your last pots is red flat worms--not something to worry about. I've had them come and go 10x in the past 15yrs--w/out treatment.

Red flat worm if your sand bed is dirty they can multiply to plague proportion. Springeri damsel will take care of them
