Yellow Longnose Butterflyfish
A brilliant yellow butterflyfish with a black eye patch and an extraordinarily long, fine snout used to pick prey from deep crevices.
Feeding
A highly specialised feeder taking small crustaceans and tube-feet from deep within rockwork. Requires live mysis, enriched frozen mysis and blackworm, several times daily. Many specimens are reluctant to accept prepared food.
Compatibility
Peaceful. Will pick at tubeworms, small ornamental shrimp and some corals. Best in a mature fish-only or lightly stocked system.
Behaviour and personality
Hovers close to rockwork, probing crevices continuously with the long snout.
Before you buy
Considerably harder to feed than the similar and much easier Forcipiger flavissimus, which is often sold under the same name.

The fish is beautiful with a striking yellow color and distinct black eye patch. It’s active and curious, constantly exploring the rockwork. Feeding is challenging—needed live mysis daily, which required extra effort. Still, it’s a rewarding addition to a well-established tank.

Aesthetic appeal is excellent. The long snout makes it stand out. It’s not easy to feed, and I had to adjust my feeding routine to include live mysis. Works well in a fish-only setup with plenty of rockwork.

Looks great in the tank. It’s peaceful and doesn’t bother other fish. The feeding requirement is high and not suitable for beginners. I found it difficult to get it to accept frozen food, so live mysis is essential.
