Hi

Pls help to ID these shell or tubes. Are they harmful to coral? Should I get rid of it?

Thanks

if population out of control will be harmful, the white foam can cover the coral and is unsightly, i use superglue the tube hole to kill it lol, but dont do it all at once cos scared ammonia spike. my 2 cents

Get some bumblebee snails . But you will need alot. Approx 5 per 100lit of water.
