Elongate Dottyback

The Elongate Dottyback is a distinctive species characterized by its unusually slender, elongated body shape that sets it apart from the more compact body form typical of most dottybacks. Its body coloration varies from reddish-brown to olive with subtle blue highlights along the dorsal region. While not the most colorful member of the family, its unique body shape and active personality make it an interesting addition to appropriately stocked reef aquariums.

In its natural habitat, the Elongate Dottyback occupies crevices and caves in coral-rich reef environments throughout the Western Pacific. Its elongated body allows it to access narrow gaps in the reef structure that other fish cannot reach, giving it an advantage when hunting small prey and when seeking shelter from predators. This species is highly territorial and will aggressively defend its chosen home crevice from any perceived intruder, regardless of the intruder's size.

In the aquarium, the Elongate Dottyback requires thoughtful planning in terms of tankmate selection due to its aggressive territorial behavior. It should be housed with assertive species that can tolerate its feisty attitude. A well-structured aquascape with numerous caves, overhangs, and crevices is essential, as providing multiple potential territories helps reduce conflict. Like other dottybacks, it will consume bristleworms and other small pest invertebrates, providing a beneficial cleaning service. It is reef-safe and will not harm corals or larger invertebrates.
