In Hawaii the Picasso Triggerfish is the state fish and known as Humuhumunukunuku apua'a. Say that three times fast. Named after the famous Spanish painter, the Picasso Triggerfish has some truly remarkable colors and patterns on its body. This triggerfish is one of the more easy going of the trigger fishes but it can still become dangerous in a tank full of smaller aquarium fish and invertebrates. You will want to provide a larger tank (75 gallon minimum) with plenty of hiding places to help reduce the aggressiveness that may well up inside this fish if it feels threatened. They can become very territorial if kept in a tank that is too small. Keep them in a larger tank with some larger tank mates and it should co-exist peacefully.
They can sometimes be the Bull in the China Shop. As they roam around, they may knock over live rock or other ornaments in the tank.
Feed your Picasso Trigger 2 or 3 times a day and provide a varied diet of frozen and live foods. They may go after fish flakes and pellets. It's important to give them small frequent feedings to prevent malnutrition and fading colors.
The Picasso triggers are susceptible to most saltwater fish disease and respond well to most of the standard medicines and treatments. Quarantine any new arrivals for a period of 2 - 3 weeks before introducing them into your main tank.
One last note, be careful when placing your hand in a tank with Triggerfish. They have a mouth full of teeth and may bite if they feel threatened.

Blue Throat Triggerfish
The Blue Throat Triggerfish is considered to be one of the least aggressive of the triggers and that is one of the reasons for their popularity in the aquarium trade.
The Clown Triggerfish can be very territorial and it's gets worse the older and bigger they get. They are pretty much not afraid of anything it seems once they reach around 5 or 6 inches in size. When they are smaller they may be a bit more reclusive and will appreciate having hiding spots and places to lock into at night with their dorsal fins.
The Niger triggerfish can get to be over 12 inches (30 cm) with some of the biggest being found in the ocean up to 18 inches (46 cm)! Given their potential adult size not many home aquariums are big enough to keep them in groups. Even keeping just one though you need at least a 180 gallon fish tank.
