Overview

  • Commonly known as the Sargassum Triggerfish or Blue Throat Triggerfish.
  • Native to the Western Atlantic, including the Caribbean and Gulf of Mexico.
  • Recognized by its streamlined body, blue throat marking (in males), and spotted pattern.
  • One of the more peaceful species of triggerfish, suitable for large aquariums.

Feeding

  • Omnivorous diet, consuming both meaty and plant-based foods.
  • Requires a varied diet including shrimp, squid, mussels, and marine pellets.
  • May also graze on seaweed and marine algae.
  • Providing hard-shelled foods like clams helps maintain strong teeth.

Habitat

  • Typically found in deep reef environments and open waters near floating debris.
  • Prefers warm, stable water conditions with moderate to strong currents.
  • Requires a minimum 125-gallon tank due to its active swimming nature.
  • Needs rock formations and caves for shelter, along with ample open swimming space.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C).
  • Ideal pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
  • Regular water changes and strong filtration are necessary for maintaining water quality.
  • Generally hardy but may be sensitive to poor water conditions.
  • Requires a secure tank lid as it is known to jump.

Compatibility

  • One of the more peaceful triggerfish species but may still show aggression.
  • Can be kept with other large, semi-aggressive fish like tangs and angelfish.
  • Not recommended for small or delicate reef fish.
  • May nip at invertebrates, so caution is needed in reef aquariums.

Aquarium Behavior

  • Active and inquisitive swimmer that explores its surroundings.
  • Often hovers near rock formations and can use its powerful jaws to move objects.
  • Generally peaceful but can become territorial if space is limited.
  • Providing a diverse diet and an enriched environment encourages natural behavior.
