The Red Thorny Sea Star is a charismatic species, distinguished by its thick, gray body and bright red tubercles. These protrusions are connected by red stripes, creating the appearance of a grid-like pattern on its back. Found in shallow tidal pools and up to 100′ deep reefs in the Caribbean Ocean, this species is a captivating sight to behold. Additionally, its hardy nature makes it an ideal inhabitant for a wide range of aquatic environments. With its vibrant colors and resilient nature, the Red Thorny Sea Star is truly a remarkable species.

The Red Thorny Sea Star is a unique and interesting addition to any aquarium. It requires a large tank with ample supplies of live rock to survive. Its diet consists mainly of algae when it is a small specimen, but as it grows older it becomes more of a predator and should not be reef compatible due to its tendency to consume soft corals, sponges, tubeworms, clams, starfish, and other invertebrates. Additionally, it should not be housed with puffers as it is likely to cause harm. As such, it is important to research the species before purchasing to ensure that the aquarium environment is suitable.

The Red Thorny Sea Star is a very sensitive species that requires specific water conditions to live. The drip acclimation method is recommended for all Sea Stars due to their intolerance to changes in water chemistry. It should never be exposed to air while handling.
