Humu-Humu, Aculeate, Lagoon, Pig-Nosed, and Blackbar Triggerfish are only some of the common name of Rhinecanthus aculeatus is the true Picasso Triggerfish, not to be mistaken for the Rhinecanthus regtangulus species which is "tagged" with this same common name. In hawaii this fish is called Hu-mu hu-mu nu-ku nu-ku a pu-a-'a. Both the Rhinecantus aculeatus and rectangulus bear this famous long Hawaiian name. Roughly translated this name means "fish with a pig-nosed face". In short, this and most all other Triggerfishes worldwide are referred to commonly as Humu-Humu's, and sometimes incorrectly as Huma-Huma's, but these names do not actually identify an individual species one may have.

The Picasso Trigger is a magnificent and very popular aquarium species that is easily recognized by its creamy grayish-tan and white colored body splashed with many distinctive bright blue and yellow fine-line, and golden, black and white wide-band type markings.

This species can be found in the island of Hawaii and the Marquesas Islands westward through central Polynesia, Micronesia, Melanasia, and the Philippines in bankerohan river to be exact and around samal island to the coast of China, through the East Indies, and across the Indian Ocean to the coast of Africa and the Red Sea.

The Average size of an adult triggerfish is almost 9 to 10 inches. If you are planning to make this as a pet then you need to have 75 gallon tank and above to have more space. To maintain a peaceful tank that houses triggerfish, be sure to provide lots of room and a cave or rocks for a retreat area. Also house appropriate fish together that have similar needs and can hold their own. In this case larger protein eaters such as groupers, surgeonfishes, and basses, Some eels and puffers can be appropriate too.The Picasso Triggerfish or Huma Huma Trigger are known to have a pretty good disposition for a trigger and are generally a peaceful fish.This fish enjoys the shallower waters inside and outside the reef where lots of rocks and creviced structures are present to hide in and search for food from. To help to reduce aggression towards other tankmates, provide ample room and shelter to allow this fish to establish an adequate sized territory of its own.Not recommended. This fish eats a wide variety of crustaceans and other invertebrates, with the exception of stinging anemones such as the Stichodactyla or Carpet species for example.
Characteristics & Compatibility:

The characteristics and compatibility of Picasso species behaves in the typical aggressive Triggerfish manor. However, it may be housed with members of the same genus, if they are all added at the same time and ample space and housing is provided. Same species juveniles can be kept together, but as they mature fights are likely to occur between them. The Picasso Trigger is best kept in an aquarium with other similarly aggressive species of the same size or larger, as it may opportunistically eat smaller fish.
