hinecanthus aculeatus is the scientific name for the Picasso Triggerfish, also known as the Lagoon Triggerfish. It's a very distinctive and popular fish, especially in the aquarium trade. Here's what makes them so interesting:

• Appearance: They have a striking color pattern with bright blue, yellow, black, and white markings. This is what gives them the "Picasso" name, as it resembles the abstract style of the famous artist.
• Habitat: They are found in the Indo-Pacific region, living on coral reefs and in lagoons.
• Diet: Picasso Triggerfish are omnivores, eating a variety of things like invertebrates, algae, and even small fish.
• Temperament: They can be quite aggressive, especially when defending their territory. This is something to keep in mind if you're thinking about keeping them in an aquarium.
• Unique Features: Like other triggerfish, they have a strong jaw with sharp teeth, and a prominent dorsal fin that can be raised and locked into place.
