Fish (mob)

"You're not the only new explorer of the updated oceans, mind. We've filled the seas with new types of fish! Above is the delightful pufferfish, which filled me with delightful poison because I was too busy taking that screenshot to swim away in time :("

- Tom Stone

Fish are common passive mobs found in oceans and rivers. They come in 4 main variants: cod, salmon, puffer fish, and tropical fish.

Spawning
Cod spawn in normal, cold, and lukewarm oceans.

Puffer fish and tropical fish spawn in lukewarm and warm oceans.

Salmon spawn in cold and frozen oceans, and unlike the other 3 variants, can also spawn in rivers.

Drops
Fish drop 1 of their item form when killed: raw cod, raw salmon, pufferfish or clownfish. The drop will never be cooked, even if the fish is killed while on fire. A tropical fish will drop clownfish no matter what its type, pattern or colors are.

Behavior
Cod, salmon and tropical fish tend to swim in schools of fish (a maximum of nine cod, six salmon, and nine of the same tropical per school). Salmon are able to jump up waterfalls.

Weaknesses
None of the fish are able to survive out of water. Outside of water, they flop around for a while until eventually they die of suffocation damage. Cod, salmon and tropical fish will flip around on their sides.

Fish have a weakness to weapons that have the Impaling enchantment, which also affects squids, guardians, and elder guardians.

Defenses
Puffer fish will puff up when approached by a player, going from unpuffed, then semi-puffed, to fully puffed. Puffer fish are technically passive mobs but going near one when fully puffed will inflict the player with seven seconds of, and touching them in their puffed form will deal some damage separate from the poison.

These result in 3072 naturally-occurring combinations. With commands, the player can summon tropical fish without patterns, giving a further 32 possible combinations.
