General Description
The Zebra blenny, scientifically known as Omobranchus zebra, is a member of the Blenniidae family, specifically belonging to the Omobranchus genus. This species originates from the Indo-West Pacific region, including countries such as India, Malaysia, Indonesia, Singapore, and the Philippines. Zebra blennies typically grow up to approximately 6.0cm in size and have a striking striped pattern, hence their common name.
Aquarium Suitability
Zebra blennies are deemed suitable for specialized aquarium setups due to their specific care requirements and temperament. They are known to be aggressive towards other fish species, making it crucial to house them with caution. Keeping them with peaceful or docile species is not advisable. These fish thrive in brackish water conditions, requiring a lower salinity level compared to typical reef aquarium inhabitants.
Demands, Care and Hardiness
In terms of hardiness, Zebra blennies are considered average. To alleviate their aggressive behavior to some extent, regular feeding, ample hiding spots, and sufficient space in the aquarium are crucial. They are known to do well in tanks with a minimum volume of 150 liters and tend to adapt well to captive environments.
Reef Suitability
Zebra blennies are deemed reef-compatible, posing no harm to coral reefs or other invertebrates typically found in reef setups. Their behavior and diet do not interfere with the delicate balance of reef ecosystems, making them a safe addition to reef tanks.
Aquarium Setup
When setting up an aquarium for Zebra blennies, it is essential to replicate their natural brackish water habitat. Maintaining a salinity level ranging from 1.020 to 1.025 is crucial for their well-being. Additionally, ensuring a pH level between 8.1 and 8.4, carbonate hardness (KH) of 8-12, and a temperature range of 22.2-25.6°C will help create a suitable environment for these fish.
Behaviour
Zebra blennies are known for their aggressive temperament towards other fish species. They exhibit territorial behavior and may display aggression, especially when housed with more passive tank mates. Providing sufficient hiding spots and creating territories within the aquarium can help mitigate potential conflicts.
Feeding and Diet
These fish primarily feed on small crustaceans like krill, mysis, and artemia. Additionally, they consume zooplankton such as Cyclops and pods. A varied diet rich in these foods will help ensure the nutritional needs of Zebra blennies are met in captivity.
Dimorphism and Captive Reproduction
Zebra blennies have not been specifically noted for dimorphism or captive reproduction in available information.
Habitat and Distribution
Zebra blennies are native to the East Indian Ocean, Australia, Indonesia, and the Central/West Pacific region. They are commonly found near coastal areas with brackish water conditions and rocky substrates, where they can seek shelter and establish territories.
