The Bluestriped Fangblenny (Plagiotremus rhinorhynchos) can be found throughout the Indo-Pacific Ocean. They are parasitic by nature, eating the skin off of other fish. They mimic the movement and colors of other species, attempting to get closer. Once within range, they will quickly bite the prey with their serrated teeth, then return to their tunnel for safety. Their bite contains an opioid-based venom that reduces the pain of the bite, but also reduces the victim's blood pressure, causing disorientation. While not common, there are records of them attacking divers.

Bluestriped Fangblenny Habitat


The Bluestriped Fangblenny is native to the Indo-Pacific region and is found explicitly in coral reefs, rocky outcrops, and lagoon areas. It prefers areas with numerous hiding spots, such as crevices and small caves within the coral formations.


Bluestriped Fangblenny Reef Compatibility


The Bluestriped Fangblenny is generally considered reef-safe. It is known to be parasitic and takes small bites of scales and skin off of other fish. It coexists peacefully with various corals and is not known for nibbling on their polyps or damaging the reef structure.


Bluestriped Fangblenny Size and Lifespan


These fish are relatively small, with a maximum size of around 4 inches (10 centimeters). In captivity, they can live for several years, often reaching up to 5 years or more with proper care.


Bluestriped Fangblenny Diet in Captivity


Bluestriped Fangblennies are naturally predatory and should be provided with a diet rich in meaty foods. This can include high-quality frozen foods, live or enriched brine shrimp, mysis shrimp, and finely chopped seafood. They are not known as herbivores and should not be expected to graze on algae like other marine species.


Bluestriped Fangblenny Aquaculture Availability


Bluestriped Fang blennies are not commonly aquacultured in the ornamental marine fish trade. Most specimens available to hobbyists are collected from the wild, so sourcing them from responsible and sustainable suppliers is essential.
