The Red Marble Starfish, also known as the Tile Starfish, is among the more prevalent species within the Fromia family, distinguished by its striking coloration. Its central disc exhibits shades ranging from orange to deep red, while its arms are adorned with cream-colored spots and a red border.

These starfish can be found dwelling over sandy substrates, clinging to rocks, and occasionally climbing on anemones. They are diligent foragers, continuously on the lookout for micro-organisms and detritus as a food source, making live rock an essential component of the aquarium setup. Typically, they lead a solitary existence, but in a sufficiently spacious aquarium, multiple individuals of the same species can coexist harmoniously.

The Tile Sea Star is notably sensitive to sudden changes in oxygen levels, salinity, and water pH, and it should not be exposed to copper-based medications. When introducing it to a new environment, the drip acclimation method is strongly advised due to its susceptibility to fluctuations in water chemistry. Additionally, it's crucial to handle this starfish without exposing it to air.

To maintain their health, it's recommended to supplement the Tile Sea Star's diet with small portions of shrimp, mussels, or flaked food. This dietary variety ensures their nutritional needs are met for a thriving presence in the aquarium.
