Tailspot Blenny

The Tailspot Blenny (Ecsenius stigmatura) is a peaceful species that is reef-safe, admired for its small size, bright orange coloration with a characteristic black spot at the base of the tail, expressive “perching” behavior, and ability to graze on algae.

Males typically exhibit slightly larger size, more vibrant coloration, and sometimes display fin extensions during courtship or territorial behavior, while females/juveniles are smaller with subtler coloration.

They reach about 2.5 inches in adult size and should be housed in aquariums of at least 10–20 gallons. Provide ample live rock with algae growth, caves/hiding spots, and some open swimming space, along with stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4). A secure lid is essential since they are prone to jumping.

Diet should consist of algae (film and microalgae), spirulina, marine pellets, mysis shrimp, brine shrimp, copepods, and other prepared foods. With proper care, this fish makes a hardy, active, and personality-filled addition to reef 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.
