Juveniles may also occur around mangrove environments. Rather than being restricted to exposed coral reefs, the Narrow-Lined Pufferfish naturally favors relatively protected shallow-water habitats where it searches the bottom for small invertebrates and other food.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eReaching approximately 12 inches as an adult, this is a substantial marine aquarium fish best suited to a spacious fish-only or fish-only-with-live-rock aquarium.
