Humu Picasso Triggerfish (Rhinecanthus aculeatus) Care
The Humu Picasso Triggerfish, Rhinecanthus aculeatus, is also known as the White-banded Triggerfish and Humu Humu Triggerfish. These fish come from the Indo-Pacific and Eastern Atlantic. They have a tan body with a blue band over the upper mouth and across the head, a yellow stripe from cheek to cheek, and dark bands on the lower, back part of the body.
Triggers are carnivores and require a diet rich in meaty foods, such as brine and mysis shrimp and pieces of high-quality seafood like squid, clams, shrimp, fish, and scallops. One of their favorite foods is live urchins.
Humu Picasso Triggers can reach up to 10″ and require an aquarium of at least 180 gallons with plenty of live rock with hiding places. They are aggressive and should not be kept with very peaceful, slow-moving fish. They are best kept in a fish-only aquarium.
They are not reef safe.
