General Description
The Blue-dashed rockskipper, also known as False mudskipper, Blue-streaked blenniella, Bullethead rockskipper, or Peppered blenny, belongs to the Blenniella family within the broader Blenniidae category. Indigenous to the Indo-Pacific region, from the Red Sea to South Africa, east to the Marquesas, and north to the Ryukyu Islands, this species showcases an oblong shape and a distinctive long dorsal fin.
Aquarium Suitability
Considered suitable for most aquarium setups, the Blue-dashed rockskipper thrives in well-established tanks of at least 300 liters. They are generally hardy and adapt well to captive environments but may jump out of open aquariums, necessitating secure housing. When adequately fed, these fish are known to be reef safe, although they may nibble on soft coral and LPS if food sources are lacking.
Demands, Care, and Hardiness
This species is renowned for its peaceful temperament but can display aggression towards similar species. They prefer water conditions with a pH range of 8.1-8.4, dKH of 8-12, specific gravity between 1.020-1.025, and temperatures maintained between 22.2-25.6°C. It is crucial to ensure the presence of well-established algae in the aquarium to support their diet.
Reef Suitability
The Blue-dashed rockskipper is often deemed reef-safe, provided they are adequately fed and algae-rich environments are available in the tank. They may consume detritus and microalgae, such as spirulina, contributing to the ecosystem within a reef aquarium setting.
Aquarium Setup
For optimal care of the Blue-dashed rockskipper, aquarists should maintain a well-run tank where the fish can graze on algae present on rocks and stones. In cases where natural algae growth is insufficient, supplementing their diet with algae-rich foods like spirulina is recommended.
Behaviour
These blennies are recognized for their amusing personalities, making them an engaging addition to both small and large aquariums. They are not typically vividly colored but can captivate enthusiasts with their intriguing behaviors, including their grazing habits and interactions within the tank.
Feeding and Diet
Feeding these fish a diet consisting of small crustaceans like krill, mysis, and artemia, along with zooplankton such as cyclops and pods, is essential for their well-being. Supplementing their diet with algae-based foods like spirulina helps ensure they receive adequate nutrition in captivity.
Habitat and Distribution
In their natural habitat spanning the East Indian Ocean, West Indian Ocean, Australia, The Red Sea, Indonesia, and the Central/West Pacific, the Blue-dashed rockskipper thrives in diverse aquatic environments. Their distribution ranges from the Red Sea in the west to regions in the Pacific Ocean, showcasing their adaptability across various marine ecosystems.
