Koi

C tier

Koi are ornamental colour forms of common carp bred for ponds and display, not as a primary food fish—though they are the same species and technically edible. Flesh resembles other carp but animals raised as pets may carry treatments or unknown pond chemistry; food-grade sourcing matters if ever used in the kitchen. In practice, koi belong in garden ponds, not on restaurant menus. Where cultural or survival cookery uses carp of koi lineage, purge thoroughly and treat as common carp. Do not assume ornamental stock is safe or legal to harvest for food.
