|Minimum Tank Size:
Balistapus undulatus. This very pretty and hardy fish has a bluish green body with slanting orange lines on the rear of the head and throughout the body. There’s also slanting blue and orange stripes from around the mouth to below the pectoral fins and a large round black mark at the peduncle. Yet it’s rarely seen in the general trade/local shops because it's the most aggressive of all triggerfishes! It fact, its highly recommended this species be maintained by itself as it will attack even much larger fish and invertebrates of all types. Simply not safe with any type tankmates, nor interior aquarium equipment, e.g., hoses, electrical wiring, etc. May even disfigure, using its teeth, aquarium side panels, glass or acrylic.
