The Humu Picasso Triggerfish (Rhinecanthus aculeatus) is an iconic marine species celebrated for its distinctive geometric markings, vibrant blue and black facial stripes, and striking yellow-orange accents. Reaching a maximum length of 25–30 cm, this active carnivore brings vibrant personality and unmatched visual presence to a dedicated predatory setup.

Due to its territorial nature and powerful jaw structure, this species thrives best in a spacious aquarium of at least 681 L equipped with sturdy rockwork. It requires a varied carnivorous diet featuring hard-shelled foods to naturally wear down its teeth and must be housed with robust, non-timid companions.
