I seem to have these white circular tubes appearing all over the back of my tank. They look similar to a calcareous tube. I can't take a good picture because they are to small. Does anyone have any idea what they could be?
Thanks!

sounds like a typical filter feeding worm that shows up in LR and migrates to the glass as they reproduce.
dont worry they are harmless filter feeders if they start to get annoying you can scrap them off easily without a problem.
