Bat Stingray

The Bay Stingray (Myliobatis californica) is a semi-aggressive species that is not reef-safe, admired for its smooth, flattened body, striking grey-brown coloration with subtle patterning, broad pectoral fins resembling a “bay” shape, and active swimming behavior.

Males typically have slightly smaller disc diameters, narrower tails, and more active exploratory behavior, while females/juveniles are larger-bodied, more docile, and grow steadily over time. They reach about 30–36 inches (disc width) and should be housed in aquariums of at least 500+ gallons, due to their size and swimming needs.

Provide a fine sandbed (to protect their ventral surfaces), minimal live rock arranged to leave open swimming space, and hiding spots or gentle caves for resting. They thrive in stable water parameters (salinity ~1.020–1.025, temperature ~72–79°F, pH ~8.1–8.4), and a secure lid is recommended since stingrays can jump when startled.

Diet should consist of mysis shrimp, brine shrimp, small crustaceans, chopped seafood (squid, clam, shrimp), and high-quality meaty pellets. With proper care, the Bay Stingray becomes a striking and impressive centerpiece for advanced marine aquariums, requiring dedicated tank management and space.

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.
