Care notes
Laterally compressed body lets it fit into tight rock crevices hunting small fish and invertebrates. Grows slowly — patience required. Yellow variant is the most popular color form. Hardy and long-lived.
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.
