Just noticed these black worms?

[neo1738]

Just noticed these guys all over my live rock today. Also noticed some slime? Overall tank has been doing well just dod water testing earlier which shows higher PO4 (was due for gfo change today which I did) but otherwise pretty stable for my tank.

Temp 77.7
Alk 9.3
PO4 0.15
Mag 1375
Ca 380


Any ideas?

Side note my tank back wall is growing corraline like crazy but it seems the rocks have lost some color. Corals including SPS are all doing well.

if you can take a video and show us if they move or not, my first guess is vermetid snails.

They don't seem to move much if they do.

They don't seem to move much if they do.

then im guessing they are vermetid snails. do you see some kind of string coming out of any of them?

Also thought those had tubes they lived in these are all over the rock itself. No even w feeding. Only see then out at night.
