Lined Puller

Pycnochromis lineatus

Pycnochromis lineatus, known as the Lined Puller, is a small reef fish found in the tropical waters of the Indo-Pacific region. It inhabits areas from Christmas Island to the northern Great Barrier Reef of Australia, including Indonesia, the Philippines, Palau, New Guinea, New Britain, and the Solomon Islands. This species is typically found at depths ranging from 2 to 35 meters, often residing near the upper edges of outer reef slopes where coral growth is abundant. Divers may encounter this fish either alone or in loose aggregations, particularly near the entrances or ceilings of large caves. The Lined Puller reaches a maximum length of 7 cm and is characterized by its compressed body shape. It has 12 dorsal spines, 11 to 12 dorsal soft rays, 2 anal spines, and 11 to 12 anal soft rays. This species is diurnal and exhibits distinct pairing during breeding. It is oviparous, with eggs that adhere to the substrate. Males play a role in guarding and aerating the eggs, ensuring their development. While the Lined Puller is occasionally seen in the aquarium trade, it poses no threat to humans and is considered harmless. The species is classified as Least Concern by the IUCN.
