Blackfin Coral Goby

Blackfin Coral Goby (Paragobiodon lacunicolus) is a peaceful species that is reef-safe, admired for its compact size, velvety brown to black coloration, contrasting black fins, and its tendency to live symbiotically among branching SPS corals such as Acropora. Males typically are slightly larger and may become more territorial during breeding, often guarding egg clusters within coral branches, while females/juveniles tend to be smaller, more reclusive, and exhibit similar coloration. They reach about 1.2 inches and should be housed in aquariums of at least 10 gallons.

Provide branching live coral (ideally Acropora), plenty of live rock, and low-flow zones for perching, stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4), and a secure lid since many gobies are prone to jumping. Diet should consist of finely chopped meaty foods like mysis shrimp, enriched brine shrimp, copepods, and micro pellets, and with proper care this fish makes a standout addition to the aquarium.

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.
