Notes from the editors

What it looks like. Sleek triggerfish body with subtle yellow fin margins and (in adult males) a distinctive blue throat patch that intensifies during display. Less aggressive coloration than most triggers.

In your tank. The most reef-safe triggerfish — feeds on zooplankton in the wild and ignores most corals and inverts in captivity. Open water swimmer rather than rockwork-rearranger.

Care notes. Pairs work in 150+ gallon systems and display courtship behaviors. Aggressive toward other triggers and similar-shaped fish.

Sourcing and feeding. Wild-collected from Indo-Pacific reefs; mid-priced ($60–150). Carnivore — mysis, krill, squid, prepared meaty foods.
