Japanese filefish

The Japanese filefish (Paramonacanthus japonicus) is a marine fish characterized by its unique, elongated body and rough, sandpaper-like skin. It is primarily olive to brown in color, often with patterns or markings that help it blend into its surroundings. This species is native to the Western Pacific, particularly around Japan, where it is commonly found among reefs and seagrass beds. The Japanese filefish is not particularly well-known in the aquarium hobby, partly due to its specific dietary and habitat needs, making it a less common choice for casual aquarists.
