Description
A large, territorial marine trigger with electric blue lines across a bold olive-to-yellow body. Highly aggressive and best suited for species-only or predator tanks with ample space and reinforcement.
Difficulty Level
Expert Only
Region
Bluelined Triggerfish (Pseudobalistes fuscus)
Core Details
Highlights
Care Level
/ 10
Extremely territorial and powerful. Requires a very large, secured system and expert-level compatibility planning.
Environment Impact
/ 10
Wild-caught with minimal captive breeding. Regional collection impacts vary—choose responsibly sourced specimens when possible.
Origin
Native to the Indo-Pacific region, including the Red Sea, Great Barrier Reef, and coastal East Africa.
Visual & Functional Appeal
Striking neon-blue lines crisscross a golden-olive body, especially vibrant in juveniles. Adult coloration darkens but retains vivid striping. Thick, stocky body and commanding presence dominate large aquariums.
Purpose
Acts as a centerpiece predator in FOWLR or species-only setups. Adds raw energy and bold personality to high-impact marine tanks.
Importance
Not for casual keepers. Offers dynamic motion, visible intelligence, and behavior-rich interaction in well-managed predator systems.
Included Resources
Heavy rockwork, open swimming zones, tight lids, and industrial-strength filtration. Requires protein skimming and biological redundancy due to bio-load.
Best Use Cases
Predator tanks, public displays, or experienced marine keepers managing large aggressive species. Not reef-safe or invert-safe.
Conservation Context
Wild populations are stable, though overcollection in some reef zones is a concern. Promoting ethical capture and transport is essential for welfare.
Ideal Aquatic Animals
• Large lionfish
• Groupers and snappers
• Puffers and eels
• Other large triggers (with caution)
• Never keep with crustaceans, coral, or small passive fish
