Hey guys, these random white spots showed up this morning on the back glass of my tank. I have no idea what they are and they certainly were not there last night. I picked at one with my finger and it popped off and left a ring on the glass.
Should I worry about these or are they ok?

Probably spirobid worms and yes they're good filter feeders :). A good sign of a healthy tank

No problem with them as stated above. Most of the times the fish will pick them off.
