Zebra Dartfish (Nemateleotris decora) Care Guide:
The Zebra Dartfish, also known as the Decorated Dartfish, is a striking and peaceful marine species with a slender body, bold black-and-white stripes, and bright yellow accents. Native to the Indo-Pacific reef regions, it thrives in well-established saltwater aquariums of at least 30 gallons with plenty of live rock, crevices, and hiding spots. Ideal water parameters include a temperature of 72–78°F (22–26°C), pH 8.1–8.4, and specific gravity of 1.020–1.025. They are omnivorous, feeding on small meaty foods such as mysis shrimp, brine shrimp, and high-quality frozen or flake foods. Generally peaceful, Zebra Dartfish can be kept singly or in pairs, but multiple males may display aggression. Their darting behavior and need for secure hiding places make them best suited for a calm reef or marine community tank.
