Chocolate Chip Starfish

Protoreastor nodosus


(4 Reviews)

The Chocolate Chip Starfish, Protoreastor nodosus, also known as the Horned Starfish, features small horn-like projections from its appendages. It has a short and stout body with short and thick arms along with those knobs which resemble chocolate chips - its size and knobs make it almost impossible to swallow whole. 
 The Chocolate Chip Star eats by excreting their stomach out onto their prey and retracting it back in. They will primarily eat an omnivorous diet consisting of dead plants, algae, sponges, and detritus. Like many other starfish, the Chocolate Chip Star is highly sensitive to water quality conditions and can never be exposed to open air. They should not be paired with predatory fish or with soft corals, tubeworms, and clams as they can eat them. They  require a tank with plenty of sand, rock, and algae.

I only purchase the Chocolate Stars for my Harlequin Shrimp. So they don't last too long. Saltwater fish's prices are reasonable with great quality. Highly recommended.

We've had Chocolate chip stars for years and have found them to be very adaptive to medium size marine environments. They are well worth the investment and almost always attract the attention of people viewing the aquarium.

Chocolate Chip Starfish make a great addition to any tank. They are very easy to acclimate and care for, and stay very active roaming the aquarium cleaning the algae off of both the live rock and the glass.
