Longnose Hawkfish

The Longnose Hawkfish is a striking marine fish known for its red, lattice-like markings over a white body and its distinctively long, tube-shaped snout, which gives the species its name. It has a charming habit of perching motionlessly on coral or rock, watching its surroundings with quiet focus. As a carnivore, it can show a feisty, assertive side, especially when hunting small crustaceans.

About Longnose Hawkfish

The Longnose Hawkfish features red lattice markings and a long snout. It perches charmingly on coral but has a feisty side. Grows 8-13cm, lives 5-10 years; an intermediate-level fish.

7 things to know before welcoming a Longnose Hawkfish

  1. 1Perches on Rock or Coral

    Longnose Hawkfish have a natural habit of perching on coral or rock, so it helps to include sturdy live rock or coral bases they can rest on. Adding height variation to your aquascape makes it easier for them to settle into a favorite spot.

  2. 2An Intermediate-Level Fish

    The Longnose Hawkfish is generally considered an intermediate-level fish, so some prior experience with water quality management and feeding routines will help. It's a good fit for keepers who already have some marine aquarium experience under their belt.

  3. 3Feisty and Best Kept Alone

    As a carnivorous species, Longnose Hawkfish can be quite feisty and territorial, especially toward other hawkfish or similarly shaped fish. They generally do best kept alone, so if you plan to keep tankmates, consider tank size and compatibility carefully.

  4. 4Small Crustaceans May Be Prey

    In the wild, Longnose Hawkfish prey on small crustaceans, so very small ornamental shrimp kept in the same tank may end up being eaten. Choose tankmates with size and safety in mind.

  5. 5Feeds on Frozen Food and Pellets

    Longnose Hawkfish mainly eat frozen foods and prepared pellets, and they tend to adapt to feeding relatively easily. When first introducing them, try a few different foods and confirm they're eating well.

  6. 6Jumps Easily — Use a Lid

    Longnose Hawkfish can move quickly when startled and are known to jump out of open tanks. Always use a secure lid or cover any gaps in the aquarium top.

  7. 7A 5-10 Year Commitment

    Adult Longnose Hawkfish typically grow to about 8-13 cm and can live for around 5 to 10 years. Before bringing one home, it's worth confirming you can provide consistent care over that whole period.
