In nature, Pea Puffers spend their days weaving through dense vegetation and leaf litter, hunting for anything that moves. Worms, crustaceans, insect larvae,

In 2013, a wave of molecular research reshaped the pufferfish family tree. Genera once grouped under Tetraodon were split into Pao, Dichotomyctere, and Leiodon, revealing deep evolutionary divides hidden by outward similarity. This landmark reclassification transformed both science and the aquarium hobby, marking the moment when modern genetics redefined how we understand pufferfish lineage and identity.

This is the guide that changed everything. Through research, field observation, and thousands of shared experiences, this care sheet redefined what responsible keeping means. It set the benchmark for clarity, accuracy, and compassion, becoming the trusted reference for aquarists around the world.
