Common name: Tentacled flathead

General information

The Tentacled flathead, scientifically known as Papilloculiceps longiceps, is a unique and fascinating fish species that is occasionally found in the aquarium trade. It is known for its distinctive appearance, featuring a flattened body and head, with eye stalks that protrude when hunting. Its cryptic coloration and patterns allow it to blend seamlessly with its surroundings, making it an expert ambush predator.

This species is also referred to as the Crocodilefish due to its resemblance to a crocodile's head when viewed from above. The elongated tentacles above its eyes are used to enhance its camouflage and to lure prey within striking distance.

Care

Caring for a Tentacled flathead in a home aquarium requires attention to detail, as they need a sandy or rubble substrate to bury themselves and ambush prey. They are not active swimmers and prefer to remain stationary, waiting for food to come to them. A varied diet of meaty foods such as shrimp, fish, and squid is essential for their health.

Reproduction

Little is known about the reproductive habits of Papilloculiceps longiceps in the wild or in captivity. They are presumed to be egg-layers with external fertilization, similar to other flathead species.

Habitat

The natural habitat of the Tentacled flathead spans the Indo-Pacific region, from the Red Sea and East Africa to Papua New Guinea and north to Japan. They are typically found on sandy or rubble bottoms near coral reefs, often at depths where they can easily blend with their environment.
