goldfish
Let an agent explain goldfish varieties and their care, correct myths about their needs and lifespan, describe breeding and history with attribution, and address welfare and environmental issues.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain goldfish varieties and their care, correct myths about their needs and lifespan, describe breeding and history with attribution, and address welfare and environmental issues.
A freshwater fish domesticated from the Prussian carp in China over a thousand years ago and bred into many ornamental varieties, from the common goldfish to fancy forms such as the Tosakin, Celestial Eye, egg-fish and regional Japanese varieties such as Shonai and Tsugaru Nishiki; goldfish are among the most popular pet fish, can live for decades with proper care, and are also an invasive species where released.
