Regal Damselfish

The Regal Damselfish (Neopomacentrus cyanomos) is a semi-aggressive species that is reef-safe, admired for its striking blue coloration with a subtle golden sheen, active schooling behavior, and hardy nature. Males typically display slightly brighter coloration and may show territorial behavior during breeding, while females and juveniles tend to have a more subdued appearance with less intense coloring.

They reach about 3 inches in length and should be housed in aquariums of at least 30 gallons. Provide ample live rock for hiding, some open swimming space, and secure rockwork for territory, along with stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4), and a secure lid since many species are prone to jumping.

Diet should consist of a mix of meaty foods like mysis shrimp, brine shrimp, copepods, quality marine pellets, and some algae-based foods, and with proper care this fish makes a standout addition to the 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.
