Care

Bluefin Trevally are best suited for very large aquariums due to their size and active nature. They require ample swimming space and a varied diet of meaty foods such as squid, fish, and crustaceans. It's important to note that they can be aggressive towards smaller tank mates and are best kept with other large, robust fish.

Reproduction

In the wild, Bluefin Trevally form large spawning aggregations and are known for their elaborate courtship displays. In the home aquarium, breeding is rare and requires a very large system to accommodate their behavior and growth.

Habitat

Native to the Indo-Pacific region, Bluefin Trevally are found in a variety of marine environments from shallow bays to deep offshore reefs. They are often seen patrolling reef edges in search of prey and can be found at depths ranging from the shallows down to about 190 meters.
