The narrow-lined puffer is native to the western pacific in shallow lagoons and estuaries with a muddy or sandy sea floor at depths up to 60 feet. Found around the Philippines, northwest Australia, Samoa, Ryukyu Islands, New South Wales, and Tonga.

The body of the narrow-lined puffer is milky-tan in color with thin dark bands from head to tail, sometimes being faint and translucent. It is covered with small prickles and the eyes are surrounded by a caramel colored ring. The dorsal fin has 9 – 11 soft rays, with no spines, and the anal fin has 9 – 10 soft rays, with no spines.

The narrow-lined puffer will use a fused beak and teeth to crush its prey. The diet consists of small fish, squid, krill, clams, mollusks, and hard shell shrimp that will help keep the teeth worn down.

If this species is kept in captivity it should be as close to its natural habitat as possible, with structures to resemble caves and cavities for the fish to hide in, with a minimum 125-gallon tank. Use of high quality water is recommended for this fish to thrive. The narrow-lined puffer is not aggressive toward other fish, but is territorial.
