Datasheet

General Description

The Exquisite Firefish (Nemateleotris exquisita) is a colorful nano-fish species belonging to the Gobiidae family. It is closely related to the Purple Firefish but stands out with its brighter yellow hue, slender body, and distinct features such as a shorter face and dorsal fin. This species is native to the Western Indian Ocean, where it inhabits deeper waters compared to its Western Pacific counterpart.

Aquarium Suitability

The Exquisite Firefish is well-suited for aquarium life, especially in tanks of 20 gallons or larger. It thrives in environments with ample loose coral rubble for hiding and a secure lid to prevent jumping. While generally peaceful, this fish can exhibit territorial behavior, particularly towards its own species unless they form a mated pair.

Demands, Care, and Hardiness

Categorized as an easy-to-care-for species, the Exquisite Firefish requires stable water conditions with a pH ranging from 8.1-8.4, a carbonate hardness (KH) of 8-12, and a specific gravity of 1.020-1.025. It is known for its peaceful temperament and does not usually display aggression towards tank mates.

Reef Suitability

This vibrant fish is considered reef-compatible, making it a desirable addition to reef aquariums. Its peaceful nature and striking coloration complement various coral and invertebrate species without posing a threat.

Aquarium Setup

To create an optimal environment for the Exquisite Firefish, aquarists should include plenty of hiding spots, such as coral rubble, in the tank layout. A tight-fitting lid is essential to prevent the fish from leaping out. Maintaining stable water parameters and providing suitable tank mates are crucial for the overall well-being of this species.

Behaviour

The Exquisite Firefish is known for its peaceful demeanor but can exhibit territorial behavior, especially in the absence of a compatible mate. When threatened or stressed, it may retreat to hiding places within the aquarium.

Feeding and Diet

As a carnivorous species, this firefish primarily feeds on prey suspended in the water column. Its diet should consist of enriched mysis shrimp, brine shrimp, chopped seafood, and frozen carnivore preparations. Ensuring a varied and nutrient-rich diet is essential for maintaining the fish's vibrant coloring and overall health.

Dimorphism and Captive Reproduction

While information on dimorphism is limited, the Exquisite Firefish can reproduce successfully in captivity under the right conditions. Breeding pairs may exhibit specific behaviors, such as courtship rituals and nest preparation, leading to the hatching of eggs and the rearing of fry.

Habitat and Distribution

The Exquisite Firefish is native to the Western Indian Ocean, where it inhabits deeper waters. Its natural habitat includes coral reefs and rocky areas, where it can find shelter and forage for food. Aquarists aiming to replicate its natural environment should consider incorporating reef structures and suitable substrates in the aquarium setup.
