About
Various species of small-to-medium Asian Tetraodontidae are sold under the generic 'Freshwater Blowfish' trade name, most commonly comprising Dichotomyctere or Pao species. These fish share common care requirements: hard-shelled invertebrate prey, excellent water quality, and species-only housing. Buyers should request scientific identification when possible to ensure appropriate long-term care.
