The Narrow-Lined Puffer captures the essence of the specialized nature of puffers. Classic and elegant in design, the Narrow-Lined Puffer has a large, pillowy body that is predominately milky tan with thin concentric banding from head to tail reminiscent of wood grain. Smoky black accents border its drooping paddle-like caudal fin, while the iridescent eyes are outlined by a caramel-gold ring. The Narrow-Lined Puffer is an exceptional fish sure to make an endearing addition for puffer enthusiasts or anyone wanting personality in their larger, fish-only or fish-only-with-live-rock marine aquarium.
Members of genus Arothron, including the Narrow-Lined Puffer, are sometimes called “Fat Puffers” and exemplify the typical puffer design. Though lacking pelvic fins and a hydrodynamic body shape, puffers are extremely maneuverable and are tenacious and capable predators. Like many “Fat Puffers,” the Narrow-Lined Puffer displays an unusual degree of “intelligence” and “personality” and appear to quickly recognize their owners.
In the wild, the Narrow-Lined Puffer inhabits a wide range of habitats including mangrove swamps, sea grass beds and reef flats. The ideal setup should be an established aquarium 125 gallons or larger with good filtration and a protein skimmer. Aquascape liberally with live rock and other materials to create an environment rich with nooks and crannies, caves and overhangs while preserving easy access to large open areas. House with fish of similar size and temperament and be aware that the Narrow-Lined Puffer will eat invertebrates found in the aquarium using its fused beak-like teeth to crush open its prey.
The diet of the Narrow-Lined Puffer should include a variety of meaty food including squid, krill, clams, and hard shelled shrimp to help wear down their ever growing teeth.
