Tropical Fish is a raw food item in Minecraft, obtained by killing the tropical fish mob that swims in warm oceans, lukewarm oceans, deep lukewarm oceans, and lush caves, or by fishing in any water. Tropical Fish was added in Java Edition 1.13, the Update Aquatic, and drops as a single uniform item even though the live mob has 3,584 color-and-pattern combinations. Eaten raw, Tropical Fish restores just 1 hunger point (half a drumstick) and 0.2 saturation, making it one of the weakest foods in the game.

Tropical Fish cannot be cooked in a furnace or smoker — no cooked variant exists, unlike cod and salmon. The main reason players collect Tropical Fish is the axolotl: scooping one of these fish with a water bucket creates a Bucket of Tropical Fish, the only food that breeds and leads axolotls. Tropical Fish is renewable through fishing, so an AFK fish farm or a simple rod-and-hook spot beside a warm ocean keeps a steady supply for axolotl breeding and emergency food.
