General Description
The Lance blenny, also known as the Slender sabretooth blenny, belongs to the Blenniidae family. This species, Aspidontus dussumieri, can reach a maximum size of 12.0cm and is found in the Indo-Pacific region.
Aquarium Suitability
The Lance blenny is considered suitable for special aquarium setups due to its aggressive temperament towards other fish species. It is recommended to keep them on their own or in aquariums without other members of the same species. They may attack and harm other fish in the tank, making them unsuitable for community setups.

They thrive best when provided with a suitable environment that mimics their natural habitat in the wild. The Lance blenny prefers water conditions with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature between 22.2-25.6°C.
Reef Suitability
The Lance blenny is always reef safe, making it a compatible species for reef aquariums. Their behavior and feeding habits do not pose a threat to coral or other invertebrates typically found in reef environments.
Aquarium Setup
When setting up an aquarium for Lance blennies, it is essential to provide ample hiding spaces and ensure that the tank is large enough to accommodate their territorial nature. A minimum tank size of 150 liters is recommended to create a suitable living environment for these aggressive fish.
Behaviour
Known for their aggressive behavior towards other fish species, Lance blennies are territorial and should not be housed with other fish that may be targeted for attacks. Their aggressive nature extends to potential threats, including humans, as they might bite when feeling threatened.
Feeding and Diet
These fish have a diet primarily consisting of fish and zooplankton such as Cyclops and pods. It is crucial to provide a varied diet to meet their nutritional needs and ensure their health and well-being in captivity.
