Welfare conditions for fish in the aquarium trade vary enormously from capture through wholesale to retail and home keeping, with the greatest suffering concentrated at specific supply chain stages.
Fish welfare across the aquarium trade involves suffering at multiple points that consumers rarely see. The capture mortality from cyanide fishing, transport losses, retail overstocking, and death from inappropriate home care collectively represent enormous welfare harm to animals that are almost certainly sentient. Responsible aquarium keeping — captive-bred fish, species-appropriate care, and ethical sourcing — dramatically reduces but does not eliminate this welfare impact.
