Sargassum trigger Profile

The Sargassum triggerfish, Xanthichthys ringens, is characterized by its distinctive coloration, which includes shades of blue, green, and yellow, often with intricate patterns. This species is native to the Atlantic Ocean, especially around areas with dense Sargassum seaweed. It features a robust body shape common to triggerfish, and its appearance includes the signature dorsal fin that can be "locked" upright, a feature from which the "trigger" name derives. Despite its striking appearance, the Sargassum triggerfish is not a commonly kept species in the aquarium hobby, partly due to its size and specific habitat requirements.
