Common name: Arabian Dartfish

General information

The Arabian Dartfish, Ptereleotris arabica, is a small, peaceful fish known for its elongated body and striking coloration. It has a pale body with a distinctive blue-black line running from the eye to the base of the caudal fin, and its fins are often edged in vibrant blue. This species is a member of the Microdesmidae family, which includes dartfishes and wormfishes.

Care

Arabian Dartfish are suitable for both nano and larger reef aquariums due to their small size and peaceful nature. They prefer a tank with plenty of hiding places and a sandy substrate where they can retreat if threatened. These fish are jumpers, so a well-fitted aquarium lid is essential. They thrive in groups and should be kept with non-aggressive tank mates.

Their diet should consist of a variety of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood. Consistent feeding schedules and a well-maintained water quality are crucial for their health.

Reproduction

In the wild, Arabian Dartfish are known to form monogamous pairs and spawn within burrows. In the aquarium, breeding is possible but challenging, as raising the larvae requires specific conditions and diets.

Habitat

Ptereleotris arabica is found in the Western Indian Ocean, particularly around the Arabian Peninsula, including the Red Sea and the Gulf of Aden. They inhabit shallow, coastal reefs and lagoons, often seen hovering above the substrate or nestled within crevices.
