Chocolatedip Chromis

The Chocolate-Dip Chromis (Chromis dimidiata) is a peaceful species that is reef-safe, admired for its striking two-tone coloration with a dark front half and bright white tail, as well as its active schooling behavior.

Males typically become slightly larger, more territorial during spawning, and display intensified coloration, while females and juveniles tend to be smaller, less territorial, and maintain a softer color contrast.

They reach about 3–4 inches in length and should be housed in aquariums of at least 30 gallons (larger if kept in groups). Provide ample live rock for hiding spots along with open swimming space, stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4), and a secure lid since they are known jumpers.

Diet should consist of a varied mix of frozen mysis shrimp, enriched brine shrimp, copepods, high-quality marine pellets, and occasional algae-based foods. With proper care, this fish makes a hardy and visually striking addition to both 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.
