General DescriptionThe Bicolour fangblenny, also known as Plagiotremus laudandus, is a species belonging to the Blenniidae family. These fish are commonly referred to by various names such as the Yellowtail fangblenny or the Bicolor fangblenny. They are recognized for mimicking cleaner wrasses and are native to the Western Pacific, ranging from the Philippines to the Gilbert Islands and further south to locations like New Caledonia and Samoa.
Aquarium SuitabilityConsidered suitable for special aquarium setups, the Bicolour fangblenny is known for its aggressive behavior towards other fish, making it unsuitable for community tanks. They thrive better when kept as the sole representative of their species due to their tendency to attack other fish, even causing harm to their tankmates. It is worth noting that they might also exhibit aggression towards humans.
Demands, Care and HardinessRequiring a minimum tank size of 100 liters, these hardy fish prefer water conditions with a pH ranging from 8.1 to 8.4, a specific gravity between 1.020 and 1.025, and a temperature range of 22.2 to 25.6 degrees Celsius. It is advisable to provide ample hiding spots, particularly among live rocks, to cater to their need for shelter and security in the aquarium environment.
Reef SuitabilityThe Bicolour fangblenny is considered reef-safe at all times, making them suitable for reef tank setups without posing a threat to corals or other invertebrates typically found in a reef ecosystem.
Aquarium SetupWhen setting up an aquarium for Bicolour fangblennies, it is important to ensure the presence of suitable hiding places, such as live rocks, to accommodate their natural behavior. Maintaining stable water parameters within the recommended ranges and providing a well-structured environment can help create a conducive habitat for these fish.
BehaviourKnown for their aggressive temperament towards other species, Bicolour fangblennies exhibit hunting behaviors and a tendency to pick on other fish within the same tank. Due to their predatory nature, caution should be exercised when selecting tank mates to avoid conflicts.
Feeding and DietThese fish have a varied diet that includes small crustaceans like krill, mysis, and artemia, as well as consuming smaller fish. Feeding them a balanced diet consisting of fish and crustaceans will help ensure their nutritional requirements are met in captivity.
Habitat and DistributionThe Bicolour fangblenny is commonly found in the East Indian Ocean, including regions like Australia, Japan, and Indonesia. With their distribution extending to the Central and West Pacific, these fish inhabit rocky crevices and coral reefs where they can mimic cleaner wrasses to forage and evade predators.
