The White Pincushion Urchin is a great addition to a cleanup crew and will eat leftover uneaten food, detritus, and algae including undesired filamentous algae. The White Pincushion Urchin has hairy sticky filaments all over its body as well as spines. Their sticky filaments allow them to camouflage themselves by covering itself with rocks, algae, sponges, and shells.
If there is not enough algae in the tank for the White Pincushion to graze on, it should be supplemented dried seaweed.
