Picasso Lagoon Triggerfish Rhinecanthus Aculeatus
The Picasso Lagoon Triggerfish, known by their Hawaiian name as Humu-Humu, is an aggressive species of saltwater fish found in shallow reefs and lagoons across the Indo-Pacific from the Philippines to Hawaii. They are recognized as Hawaii’s state fish and are an integral part of the island diet. The fish is known for its aggressive behavior, territorial nature, and its distinctive grunting noise used as an intimidation technique to ward off predators and startle fishermen. Picasso Lagoon Triggerfish are closely related to the more common Reef Triggerfish and are known for their beauty and hardiness, making them suitable for aquarists of any skill level. However, they require specific care and tank conditions to thrive.
- Origin: Indigenous to the Indo-Pacific, from the Philippines to Hawaii.
- Feeding Habits: Picasso Lagoon Triggerfish prey on crustaceans and squid found in the lagoon or reef bed. They are known for their messy eating habits, which can lead to organic material decay in the tank.
- Aggression Level: Highly territorial and aggressive, Picasso Lagoon Triggerfish are known for violently defending their territory against intruders, including divers. They are lone fish that form harems during the breeding season, composed of a single male and multiple females.
- Suitable Tank Mates: Due to their territorial nature, it’s advisable to keep only one Picasso Lagoon Triggerfish in a tank. If attempting to keep a pair, a larger tank is necessary.
