The Humu Humu Trigger, Rhinecanthus aculeatus, is sometimes known as the Picasso Trigger.  the Humu Humu can emit an audible whirring sound. They are best kept in a large tank with plenty of  rocks and caves, as they will  rearrange the landscape and rocks as it wanders around. 

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.
