This fish forms large schools in the wild and should therefore be kept in groups of at least 6-8 fishes in the aquarium. If your aquarium is large enough, you can also include other peaceful fish species in the tank but this might lead to some aggression from the Bluelined Snapper group. Ideally introduce all the fish simultaneously since this decreases the risk of violence. Do not crowd the aquarium because this will increase the risk of aggressive behaviour. The aquarium must provide the fish with plenty of open space to swim around in. Since these fishes grow so large, they are not very common in the aquarium trade. Some aquarists keep single specimens, but living alone without a group of its own species is not natural for the Bluelined Snapper.
The Bluelined Snapper is not considered reef compatible since it is fond of eating many different types of crustaceans, such as crabs and shrimps. It will also eat small fish.
