Care notes
Striking artistic patterning. Hawaiian state fish (humuhumunukunukuapua'a). Less aggressive than many triggers but still not reef-safe. Personable and intelligent.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
