Truncate Cardinalfish

The Truncate Cardinalfish (Cheilodipterus singapurensis) is a semi-aggressive species that is reef-safe with caution, admired for its bright orange-red coloration, bold vertical stripes, compact size, and distinct truncate tail fin. Males typically display more intense coloration during breeding and exhibit territorial behavior, while females and juveniles are slightly smaller with less vivid colors and more streamlined bodies. They reach about 4 to 5 inches in length and should be housed in aquariums of at least 40 gallons.

Provide a sandy substrate with ample live rock formations and plenty of hiding spots, stable water parameters (salinity ~1.020–1.025, temperature ~72–79°F, pH ~8.1–8.4), and a secure lid as this species is prone to jumping.

Diet should consist of mysis shrimp, brine shrimp, copepods, pellets, and occasional algae-based foods. With proper care, this fish makes a striking and active addition to marine 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.
