Fish photography can be a rewarding experience, but shooting in an aquarium setting presents unique challenges. The glass, lighting, and movement of the fish all require specific techniques to capture clear, sharp, and vibrant photos. In this post, we’ll explore some practical tips to help you take amazing photos of fish in aquarium tanks.

1. Understand the Aquarium Setup
Before taking photos, take some time to understand the aquarium setup. Check the size of the tank, the type of fish, and the environment they live in. Are there plants, rocks, or decorations that you can incorporate into your photos? Understanding the layout will allow you to plan your shots better and position yourself for the best results.
Most importantly, we need to understand how the fish move and where they spend most of their time. This will help you anticipate their behavior and capture natural moments.
2. Use the Right Camera Settings
To capture clear and detailed photos of fish in an aquarium, use manual mode on your camera. Start by setting a low ISO, preferably between 400 and 800. Lower ISO settings reduce noise in your images, which is important in the controlled lighting of an aquarium.
Next, adjust your aperture to a wide setting (f/2.8 to f/5.6) for a shallow depth of field. A shallow depth of field will help blur the background and make the fish stand out in your shot. If your aquarium is brightly lit, you may need to use a faster shutter speed to prevent overexposure.
For example, if you’re photographing fast-moving fish, try using a shutter speed of 1/500 or higher to freeze the action.
3. Choose the Right Lens
Choosing the right lens is crucial for aquarium fish photography. A macro lens or a 50mm prime lens is ideal for capturing sharp details of the fish. If you’re photographing a larger aquarium, you may prefer a wide-angle lens to capture the entire scene.
A macro lens allows you to get close to the fish and take detailed shots of their fins, scales, and unique features. A 50mm lens with a wide aperture is perfect for low-light situations and helps create beautiful bokeh (blurred background).
If you’re photographing large groups of fish or capturing the whole tank, a wide-angle lens (16-35mm) will allow you to capture more of the environment without distortion.
4. Minimize Reflections on the Glass
Reflections from the aquarium glass are one of the most common challenges in aquarium photography. To minimize reflections, try the following techniques:
-
Get as close to the glass as possible: Press the lens or the camera body gently against the aquarium glass to eliminate reflections. This helps avoid distracting reflections from the lights or room around the tank.
-
Adjust your angle: If you’re unable to get close to the glass, change your shooting angle. Try shooting at a slight angle instead of head-on to reduce the reflection from surrounding lights.
-
Turn off the aquarium’s internal lights: If the tank’s lights are creating reflections on the glass, try turning them off or dimming them. This can help reduce unwanted reflections and make the fish appear clearer.
5. Use External Lighting
Aquarium lighting can sometimes be too dim or too harsh for good photography. If the lighting in the tank is inadequate, consider using external lights, such as softboxes or LED panels, to enhance the illumination. These light sources should be diffused to prevent hard shadows and reflections.
Position the external light above or to the side of the tank to create soft, even lighting on the fish. Avoid placing the light directly in front of the tank, as this can cause glare and reflections.
If you want to capture a more natural look, try using a light source that mimics daylight, such as a daylight-balanced LED bulb. This will create a more vibrant and accurate color balance in your images.
6. Capture Fish Behavior
When photographing fish in an aquarium, it’s important to capture their natural behavior. Spend time observing how the fish move and interact with each other. Some fish are more active at certain times of the day, while others are more relaxed.
To photograph these moments, be patient and ready to take the shot when the fish are in a dynamic position. For instance, if you’re photographing fish swimming together in a school, try to capture the motion and pattern of their movement. This can make your photos more exciting and engaging.
If you have a particular fish in mind, wait for the right moment when it swims to the perfect spot in the tank. By knowing their behavior, you can be ready to capture them at their best.
7. Focus on Composition
Composition is key to creating stunning aquarium photos. Use the rule of thirds, which involves placing the subject (the fish) off-center to create a more balanced and interesting image. You can also experiment with leading lines, such as the edges of plants or rocks, to guide the viewer’s eyes toward the fish.
In addition to composition, think about the overall mood you want to convey. For instance, if you want to create a peaceful atmosphere, photograph the fish swimming gently through plants or near the tank’s soft lighting. For a more dynamic look, capture the fish in mid-motion or interacting with other fish in the tank.
8. Be Respectful of the Fish’s Environment
Lastly, remember to be respectful of the fish’s environment. Avoid disturbing the tank’s ecosystem by ensuring that the fish are not stressed or frightened. Some fish may hide or become skittish when there’s too much movement around them.
Keep your movements slow and steady, and try not to use bright flashes that may startle the fish. If you notice that the fish are becoming distressed, stop shooting and give them time to calm down before continuing.
Conclusion
Fish photography in aquarium tanks can be challenging, but with the right techniques and a little patience, you can capture stunning images. By using the correct camera settings, minimizing reflections, and being mindful of the lighting, you can produce beautiful photos that showcase the unique beauty of fish. Remember to respect the fish and their environment, and enjoy the creative process as you work to capture their behavior and personality.
