Description
The Blunthead Puffer (*Sphoeroides pachygaster*) is a marine pufferfish found in tropical and temperate waters worldwide. Known for its smooth skin and blunt head, it is a predatory species that feeds on benthic invertebrates. While generally less aggressive than some other puffers, it requires careful tankmate selection or a species-specific setup.
