General information

The Zonate Dartfish, scientifically known as Pseudamia zonata, is a small and peaceful marine fish that is well-suited for community aquariums. This species is characterized by its elongated body, striking coloration with horizontal stripes, and a tendency to hover in the water column. They are not as common in the trade as some other dartfish, but their unique appearance and behavior make them an interesting choice for aquarists looking to add diversity to their tank.

Care

Zonate Dartfish require a well-established aquarium with plenty of hiding places and a sandy substrate where they can retreat if frightened. They are known for jumping, so a tight-fitting lid is essential to prevent escape. These fish thrive in stable water conditions and should be kept in groups if the tank size allows, as they are naturally social. A varied diet of meaty foods, such as brine shrimp, mysis shrimp, and finely chopped seafood, will help maintain their health and coloration.

Reproduction

In the home aquarium, breeding Zonate Dartfish can be a challenge. They are not commonly bred in captivity, and little is known about their reproductive habits. However, like many marine fish, they are likely to be pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs.

Habitat

Pseudamia zonata is found in the Indo-Pacific region, from the Maldives to the Philippines, and north to southern Japan. They inhabit coral reefs and lagoons, often seen hovering above the substrate or within branching corals. In the wild, they are typically found at depths ranging from shallow waters to about 40 meters.
