The Humu Humu Trigger, (Rhinecanthus aculeatus), also known as the Humu or Picasso Trigger, are a beautiful and well-known fish. They can be found in many locations, including the Indo-Pacific, Red Sea, coast of Africa and Hawaii. They Have a grey or white body with yellow, blue and black stripes. They are aggressive by nature and should be kept in FOWLR tanks with other fish of similar size and temperament. Reaching a maximum size of 12 inches, they do best in a tank of at least 75 gallons. They are not reef safe and should not be kept with prized crustaceans. They are carnivorous, and should be fed a variety of frozen shrimp or krill daily. 

Is definitely an aggressive fish. Any additions need to be at least his size or larger in my aquarium.

Might be my favorite fish in my tank. I got one about 1” and is the tank “tough guy”. He wanders all around the tank and when gets too close to one of my damsels spots just ignores the damsels attempts to chase him away. I just got a clown fish that clings to his side. Fun to watch and has a big personality.

Love this little fella. I know it wont be too long before it gets big. He is active and has a healthy appetite. Wonderful addition to the tank.

Love this cool-looking fish! Peaceful, with a ton of personality. He'll come up to the long handled food dispenser and nibbles from it. Sleeps in the same spot in a crevice on 1 of my live rocks. Love this fish.
