Overview

  • The longnose hawkfish wears a red-on-white crosshatch and a needle snout, and lives like its namesake: perched high on the reef, watching, then striking.
  • In the wild it sits in gorgonians and black corals at depth.
  • It is hardy, disease-resistant, and full of character — one of the most rewarding 'personality fish' in the hobby, with stocking caveats that need respecting.

Housing

  • Provide 150 litres (40 gallons) or more with tall rockwork, branching structures, or gorgonian-like decor for perching; a hawkfish without lookout posts is a stressed hawkfish.
  • It rests on its pectoral fins rather than swimming constantly.
  • It is coral-safe and fine in reefs at standard parameters: 24-26C, salinity 1.024-1.026.
  • The lid must be tight — hawkfish are explosive jumpers when startled.

Diet

  • Feed meaty foods once or twice daily: frozen mysis, krill, enriched brine, and chopped seafood, with marine carnivore pellets accepted in time.
  • The strike from a perch is fast and accurate.
  • Vary the menu; a hawkfish on one food sulks and fades.
  • They are unfussy eaters once settled, usually within days.

Health

  • Longnose hawkfish are among the tougher marine fish: thick-skinned, parasite-resistant, and unbothered by minor parameter wobbles that stress delicate species.
  • Quarantine remains best practice.
  • Most losses are jumping accidents or starvation in shipping-stressed new arrivals — confirm feeding at purchase.
  • Otherwise expect a long, robust aquarium life.

Temperament

  • It is peaceful with fish too large to swallow but a genuine predator of small, slender fish and ornamental shrimp: firefish, small gobies, and cleaner shrimp are at real risk.
  • Stock around its mouth, not its manners.
  • Keep one hawkfish per tank; two will fight for the high perch.
  • With suitable tankmates it is bold, watchful, and quickly learns to anticipate feeding — often hopping perch to perch to track its keeper across the room.

A good fit for

  • Keepers who want an interactive character fish
  • Reefs with tall rockwork and branching decor
  • Communities of mid-sized, robust fish
  • Aquarists tired of delicate marine species

Common mistakes to avoid

  • Ornamental shrimp — they will be eaten
  • Tiny slender fish disappearing one by one
  • Open lids: hawkfish jump far and fast
  • Pairing two hawkfish over one prime perch
