White spots

[Shane0f]

Bad photo but does anyone have any idea what these white spots are they are growing on the back of my aquarium glass. Started with about a dozen they have gotten bigger now and smaller ones are spreading. Would love to hear any ideas / guesses thanks

Probably just spiraloid worms or mini featherdusters

Okay never heard of spiraloid are they are pest? Should I try and get them out? I have never seen feather dusters look like that.

They are fine. Just harmless filter feeders.

 

[Shane0f]

What do you mean by filter feeders mate?

 

[Mrc8858]

They just eat little particles of food floating around in the water.

Cool thought that's what you meant we seem to use different terms in Australia gets a bit confusing sometimes lol cheers
