Red & Black Sea Star

The Invertebrate Red & Black Sea Star (Fromia sp.) is a peaceful species that is reef-safe, admired for its striking red and black coloration, star-shaped symmetry, and unique crawling behavior.

Males typically closely resemble females in size and coloration, making them difficult to distinguish visually, while females/juveniles may appear slightly smaller and lighter in color until fully mature.

They reach about 4–6 inches in diameter and should be housed in aquariums of at least 50 gallons. Provide plenty of live rock, mature sandbed, and stable surfaces for grazing, along with stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4).

Diet should consist of natural biofilm, detritus, microalgae, and supplemental feeding of small pieces of shrimp or marine meaty foods if needed, and with proper care this sea star makes a standout addition to reef and community aquariums.

International Aquatics Quarantine & Guarantee: All fish are checked by marine vets, given a formalin bath, and held for 14 days in copper-treated systems. We feed Selcon-soaked food with Kanaplex and Metroplex during quarantine. Unless marked, all livestock comes with our 15-Day Guarantee. You will receive a video of your fish eating before shipment. On request, we also send photos/videos after arrival at IA. Some species are import-to-order (3-10 business days). Many common species are already cleared or near the end of QT.

Several species will be import-to-order and may take anywhere from 3-10 business days to secure. Once your fish is secured, you will be notified, and the quarantine process will then begin.
