Golden Back Triggerfish

The Golden Back Triggerfish skipped reef-guard duty — instead of holding a territory and attacking anything that wanders too close, it schools in open water along current-swept drop-offs, filtering plankton out of the water column like it never got the aggressive-trigger memo. That gold-edged tail and dorsal fin are a genuine standout in a fish-only tank, and the temperament runs noticeably calmer than most of its cousins, though it's still a trigger underneath the good manners.
