Behavior

A schooling, pelagic fish related to jacks. Remarkable for its mirrored, disc-like body. Occasionally kept in large public aquarium tanks. Requires very large, open swimming space and excellent water quality. Groups of 3+ behave more naturally.

Diet & Feeding

Carnivore. Feeds on small fish, shrimp, and invertebrates. Offer live feeder shrimp to initiate feeding, transitioning to frozen silversides and mysis shrimp.

Cautions

Difficult to keep in home aquariums. Best in very large, minimally decorated tanks. Stressed easily by tank mates that are boisterous or by confined spaces.
