Buffalo Trunkfish

To capture high-quality footage of a Buffalo Trunkfish, you will need a dedicated underwater action camera or a trail camera with a waterproof housing rated for at least 30 feet. These fish spend most of their time near the seabed, so the best camera placement is on a weighted low-profile tripod or a sand-screw mount. Position the lens about 1 foot above the ocean floor, angled slightly upward to capture the fish's unique triangular silhouette against the lighter water column.

Lighting is the most critical factor when filming underwater. If you are setting up a stationary camera in a seagrass bed, try to do so during the middle of the day (10 AM to 2 PM) when the sun is directly overhead to maximize natural light penetration. If you are using artificial lights, place them at a 45-degree angle away from the lens to minimize 'backscatter,' which occurs when the light reflects off floating particles and makes the water look murky.

Trunkfish are curious but cautious. You can encourage them to visit your camera site by scouting for 'blow holes' in the sand—small depressions where they have recently been foraging. Placing your camera near the edge of a seagrass-to-sand transition zone is highly effective. Avoid using heavy baits, as these often attract larger, aggressive fish that will chase the trunkfish away. Instead, a slight disturbance of the sand near the camera can be enough to pique their interest as they investigate for uncovered prey.

For video settings, use a frame rate of at least 60fps. Because Buffalo Trunkfish use rapid, fluttering fin movements to stay stable, standard frame rates often result in blurry fins. A higher frame rate allows you to slow the footage down in post-production, highlighting the incredible mechanical precision of their swimming style. Ensure your white balance is set to 'Underwater' or 'Cloudy' to help counteract the blue-green tint of the water and bring out the subtle yellow and olive tones of their carapace.
