Longnose Batfish (Walking Batfish)
The Longnose Batfish, also called the Walking Batfish, has a horizontally flattened body, mottled reddish-brown to a dark tan; it may have dark spots along the sides and fins. In behavior, it is closely related to frogfish.
The Longnose Batfish has a moveable antennae-like structure on its nose. When hungry, the Longnose nearly freezes on the sea floor, moving this antennae back and forth. When a small fish gets curious and moves in for inspection, the Longnose opens its mouth and sucks in the unsuspecting victim.
The Longnose is a very poor swimmer, but has developed very strong pectoral and pelvic fins that it uses as hands and feet to creep along the sea floor. The Longnose Batfish has been seen jumping, crawling and even walking on “all fours”. When threatened, it may remain motionless or slowly retreat to the substrate.

The Longnose Batfish is a fascinating addition to my reef tank. It looks very unique with its flat body and long nose. It stays mostly still and only moves when it detects something nearby. I’ve seen it gently crawl across the substrate, which is both surprising and entertaining.

This fish is a visual highlight in my aquarium. It doesn’t eat much and seems to be content just observing the tank. The way it moves like a walking creature is very interesting and adds a natural element to the display.

I’ve had the Longnose Batfish for three months now. It’s very calm and rarely disturbs the other fish. The antennae movement when it’s hungry is quite noticeable and adds to the realism of the tank.
