About Lagoon Triggerfish
The Picasso triggerfish — bold geometric markings and even bolder personality. Will rearrange rockwork, eat anything it can fit in its mouth, and learn to recognize you. Fish-only territory; not reef-safe.
The lagoon triggerfish, also known as the blackbar triggerfish, the Picasso triggerfish, or the Picassofish, is a triggerfish, up to 30 cm (12 in) in length, found on reefs in the Indo-Pacific region.
Notes from the editors
What it looks like. Bold geometric markings — black, white, yellow, and blue patches in distinctive shapes. The classic "Picasso" pattern.
In your tank. Big personality, big appetite, big problems for inverts and small fish. Will rearrange rockwork, eat anything bite-sized, and learn to recognize you. Fish-only territory; not reef-safe in any sense.
Care notes. Aggressive toward other triggers and similar-shaped fish. Single specimen per tank under 180 gallons. Hardy and long-lived once established.
Sourcing and feeding. Wild-collected from Indo-Pacific reefs; widely available ($40–100). Carnivore — meaty foods, krill, squid, hard-shelled foods to manage tooth growth.
Care info is a starting point, not a guarantee. Individual specimens, water chemistry, and tankmate dynamics vary. Verify against multiple sources and adjust to what you observe. See our terms & disclaimers.
