The beautiful Coco Worm (Protula magnifica) is a difficult animal to keep long-term.
Tube worms are beautiful, fascinating members of the class Polychaeta. They are also the most popular polychaetes available to aquarists. Larger species are intentionally purchased and added to the reef tank because of their elegant form and or their lovely colors, while smaller species often come in with live corals (i.e., living on the rocky bases that the corals are growing on). Unfortunately, the larger species often don’t fare as well as their much-malign brethren, the bristle or fire worms.
