White Crusty Growths

[dangles]

I’ve noticed all these little white growths on the walls of my aquarium. Initially I was scraping them off as needed but then I thought maybe they were the beginnings of coralline algae (my tank is 6 months old). I took a closer look today when I removed my magnetic glass cleaner (they’re growing on that too).

When you look closer, they’re small spiral shaped crusty things. When I say small I mean like less than a millimeter. The “bigger” ones are almost shaped like macaroni. There are hundreds, maybe even thousands on the back wall.

Thoughts?

Spirobid worms. Almost everyone gets these at some point. Harmless but annoying as they seem to really multiply in dark areas.

Spirorbid worms (they're a type of feather duster worm) - harmless filter feeders, though some people consider them pests because they can be unsightly in large enough numbers.

Well that’s annoying. I thought my coralline was about to take off lol
