Sharptooth Cardinalfish

The Sharptooth Cardinalfish (Cheilodipterus sp.) is a semi-aggressive species that is reef-safe with caution, admired for its elongated body, bold vertical striping, and distinctive fang-like teeth. Males typically develop a larger jaw during breeding and may exhibit mouthbrooding behavior, while females/juveniles have a slightly smaller mouth and more slender build. They reach about 4 to 5 inches in length and should be housed in aquariums of at least 40 gallons.

Provide ample live rock with caves and hiding spots, 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 mysis shrimp, enriched brine shrimp, finely chopped seafood, and high-quality marine pellets or frozen foods. With proper care, this fish makes a striking and unique addition to a carefully planned reef or fish-only system.

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.
