Behavior
The Bluelined Snapper is a hardy, active schooling fish with bold yellow-and-blue coloration that makes a vivid display in a large aquarium. In the wild it forms large aggregations around reefs and wrecks. It is a robust, fast-growing predator that needs a spacious tank with open swimming room. It is generally peaceful toward fish too large to eat and can be kept singly or in a small group. Its brilliant color and easy care (once established) make it a popular choice for large FOWLR systems.
Diet & Feeding
Carnivore. Feeds on fish, crustaceans, and other invertebrates in the wild. In captivity readily accepts meaty foods — frozen or fresh silversides, shrimp, squid, krill, and pellets. Feed once or twice daily; avoid overfeeding as they are hearty eaters.
Cautions
Grows large with a hearty appetite and heavy bioload — needs a big tank with strong filtration. Will eat any fish or shrimp small enough to swallow; choose tank mates accordingly. An active, strong swimmer; provide open space. Best for large FOWLR or fish-dominant aquariums, not nano or small reef tanks.
