Found in the coral reefs of the Indo-Pacific, this butterflyfish is a favorite among marine aquarium enthusiasts due to its eye-catching appearance and generally peaceful demeanor. Although it’s not the easiest fish to keep, with the right care and conditions, the Yellow Longnose Butterflyfish can be a beautiful addition to your marine aquarium.
Species Overview
- Scientific Name: Forcipiger flavissimus
- Common Name: Yellow Longnose Butterflyfish
- Size: Up to 9 inches (23 cm)
- Lifespan: 5 to 7 years in captivity (with proper care)
- Natural Habitat: Coral reefs in the Indo-Pacific, including Hawaii and the Great Barrier Reef

Appearance and Behavior
The Yellow Longnose Butterflyfish is known for its bright yellow body, contrasting with its long, black-tipped snout and white head. This narrow snout helps it forage in crevices for small invertebrates, and its bold colors make it stand out in any aquarium.
In terms of behavior, this butterflyfish is generally peaceful, though it can be territorial toward other butterflyfish or fish with similar body shapes. It is best kept either singly or as a bonded pair unless you have a very large aquarium. Yellow Longnose Butterflyfish are active swimmers and will spend a lot of time exploring the tank, foraging for food.
Care Requirements
Tank Size
Due to its size and active nature, the Yellow Longnose Butterflyfish requires a minimum of 75 gallons, though larger tanks (100 gallons or more) are recommended if you plan to keep multiple fish or add tank mates. This fish needs plenty of swimming space, as well as hiding spots to retreat to when feeling threatened.
Water Parameters
As with all butterflyfish, stable water conditions are crucial for the health and well-being of the Yellow Longnose Butterflyfish. Aim to maintain the following water parameters:
- Temperature: 72°F to 82°F (22°C to 28°C)
- pH: 8.1 to 8.4
- Salinity: 1.020 to 1.025 Specific Gravity
- Ammonia/Nitrite: 0 ppm
- Nitrate: Below 20 ppm
It’s important to keep the water clean and stable, so regular water changes of around 20% every two weeks will help maintain optimal conditions.
Filtration & Water Movement
Good filtration is essential to keep the water clean for this sensitive species. A canister filter or a sump system with a protein skimmer will provide the necessary filtration without creating excessive water movement. Yellow Longnose Butterflyfish do not require strong water currents, so moderate water flow is ideal.
Feeding and Diet
In the wild, Yellow Longnose Butterflyfish feed on small invertebrates, worms, and crustaceans that they find in coral crevices. In captivity, they can be somewhat finicky eaters, especially when first introduced to a new environment. To ensure a healthy and varied diet, offer a combination of high-quality frozen or live foods like brine shrimp, mysis shrimp, and finely chopped seafood.
While they may eventually accept marine pellets or flakes, it’s important to offer them frequent meals of more natural food sources, especially in the early stages of acclimation. Feeding 2-3 times a day in small amounts will help maintain their energy levels and health.
Compatibility
Yellow Longnose Butterflyfish are peaceful by nature, making them good candidates for community tanks with other non-aggressive species. Ideal tank mates include:
Avoid keeping them with aggressive or territorial species, as the Yellow Longnose Butterflyfish can become stressed easily. They are generally reef-safe with caution, but they may nip at small invertebrates like feather dusters, tube worms, and certain corals. Monitor their behavior closely if you’re keeping them in a reef tank to ensure they’re not causing damage.
Breeding
Breeding Yellow Longnose Butterflyfish in captivity is extremely rare and challenging due to their specific environmental needs and the difficulty in replicating their natural habitat. They are pelagic spawners, meaning they release their eggs and sperm into the open water, which requires a large and specialized tank setup. Because of this, most Yellow Longnose Butterflyfish available for sale are wild-caught.
While breeding in home aquariums is unlikely, you can still enjoy observing the unique social interactions of these fish if you keep a bonded pair.
Common Issues and Health Concerns
Like many butterflyfish, the Yellow Longnose Butterflyfish can be sensitive to water conditions and prone to stress-related diseases such as Marine Ich (Cryptocaryon) and other parasitic infections. Quarantining new fish before introducing them to the main display tank is essential to prevent the spread of diseases.
Here are some key tips for maintaining good health:
- Perform regular water changes to maintain high water quality.
- Ensure they have a varied and nutritious diet to prevent malnutrition.
- Provide plenty of hiding places to reduce stress.
If your fish becomes sick, isolating it in a hospital tank and treating it with appropriate medication can prevent the spread of disease to other tank mates.
Final Thoughts
The Yellow Longnose Butterflyfish is a stunning and rewarding species for experienced aquarists who are willing to put in the time and effort required to keep this sensitive fish healthy. Its unique appearance and active behavior make it a wonderful addition to a marine aquarium, and with proper care, it will thrive and become a true showpiece in your tank.
By following this care guide, you can ensure your Yellow Longnose Butterflyfish stays healthy and happy for years to come.
