Harlequin shrimp will eat the well known pest Asterina starfish. Their primary food source are starfish and sometimes you may not have any starfish available for them. That’s why we have created the Asterina Starfish pack. 
If you have more than one harlequin shrimp, they could be eaten in a few in a days depending on your order size. Our default pack is a size of x10 Asterina Starfish but if you require more, get in touch and we will see what we can do for you.
All starfish have been aquacultured by ourselves here at AdzAquatics.
