Minimum Tank Size: A minimum of 1000 litres is recommended to accommodate its large adult size and swimming needs.
Reef Safety: No – This species is not reef safe as it may prey on invertebrates and smaller fish.
Lighting and Water Flow: Standard marine aquarium lighting and moderate water flow are suitable. Ensure stable water parameters with excellent filtration due to the fish’s size and bioload.
Placement: Provide ample hiding places and open swimming areas. A secure, well-covered tank is essential to prevent escape.
Origin: Not Provided – Tank-bred specimens are bred in captivity, reducing wild collection pressure.
