Do you agree with the following, especially the section " Their presence is a sign of a healthy system" -
This group of snails have forgone their mobility by attaching their "shell" to the substrate and converting it into a calcerous tube. They release a mucus web out into the water, which they then reel back in and consume, eating the food particles caught in it. Their presence is a sign of a healthy system and don't typically cause any problems. The exception is if the mucus net irritates a neighbouring coral, which can lead to death of the polyps that it is irritating.
