Ritteri Anemone

Ritteri Anemone ([Radiantus magnifica]), a semi-aggressive species that is reef-safe with caution, admired for its vibrant coloration, long flowing tentacles, large size, and ability to host clownfish.

Males typically are similar in appearance to females but may be slightly smaller and less robust, while females/juveniles tend to have shorter tentacles and more muted coloration. They reach about 12–16 inches and should be housed in aquariums of at least 50 gallons.

Provide a sandbed, live rock for attachment, some hiding spots, and open swimming space. Maintain stable water parameters: salinity ~1.020–1.025, temperature ~72–79°F, pH ~8.1–8.4, and a secure lid, since many anemones are prone to moving or “jumping” out of the tank.

Diet should consist of meaty foods such as mysis shrimp, brine shrimp, copepods, and small pellets, and with proper care, this species makes a standout centerpiece in a marine aquarium.

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.
