"Protula bispiralis
The Hard tube "Coco worm" from Indonesia is a popular and expensive creature that is not recommended for the beginner. Its life span is not very long in captivity, usually not more than two years, and often much less than that. It has not been reported to reproduce in captivity. One should provide sufficient calcium and alkalinity for it to build its calcareous tube, and plenty of food, such as liquid invertebrate foods, live phytoplankton, or spray-dried phytoplankton. "
If this is true, you should document and report it!!
