Common name: White-tailed chromis

General information

The Black Axil Chromis, Chromis leucura, is a small and peaceful marine fish known for its striking appearance and active swimming behavior. It is characterized by its shimmering blue-green body and distinctive black spot at the base of its tail, which gives it its common name. This species is a member of the Pomacentridae family, which includes damselfish and clownfish.

In the wild, Black Axil Chromis are often found in large schools, which can create a mesmerizing display in the water. They are a popular choice among reef aquarium enthusiasts due to their hardiness and the dynamic presence they add to a tank.

Care

Black Axil Chromis are relatively easy to care for, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with stable water conditions and plenty of swimming space. These fish are not overly aggressive, but they do appreciate having their own territory within the tank.

A varied diet of meaty foods, such as mysis shrimp and finely chopped seafood, along with high-quality marine flake and pellet food, will help maintain their vibrant colors and overall health.

Reproduction

In the aquarium, Black Axil Chromis may spawn if they are kept in a group with a balanced male-to-female ratio. They are egg-layers, and the male will typically guard and aerate the eggs until they hatch. Raising the fry can be challenging and requires a separate breeding tank with appropriate food, such as rotifers and baby brine shrimp.

Habitat

Black Axil Chromis are native to the Indo-Pacific region, where they inhabit coral reefs and lagoons. They prefer areas with strong water movement and are often found at depths ranging from the surface to about 12 meters. Their natural habitat includes regions from the Red Sea and East Africa to the central Pacific Ocean.
