Direct answer
King fish are the rare end-of-ladder catches in Starsand Island: the guides list six king species by name, requiring a golden rod or better and a boat for the ocean kings, while one guide video counts seven.
Direct answer
The collected fish tables list six king fish by name: Arapaima (King), Long-barbelled Dragonfish (King), Glowfish (King), Megamouth Shark (King), Paddlefish (King), and Swordfish (King). One guide video says in total there are seven kingfish species, which does not match the six named in the tables, so this page reports the conflict rather than choosing a count. Catching them requires a minimum golden rod, and the ocean species require taking a boat to their fishing ground.
Which fish are king fish
Swordfish (King) is found in the Coral Sea all year from 6:00 to 18:00 with meat bait and sells for 826 coins. Paddlefish (King) is a river fish in Spring and Winter from 6:00 to 22:00 with bug or veggie bait, selling for 733. Arapaima (King) is a river fish in Summer and Autumn from noon to 2:00 with veggie or meat bait, selling for 782. Long-barbelled Dragonfish (King) lives in Celestwave, is available all year from 20:00 to 2:00 with meat bait, and sells for 1,051. Megamouth Shark (King) lives in Luminwave, all year from 20:00 to 2:00 with meat bait, selling for 1,051. Glowfish (King) is in Spore Cascade in Autumn from 0:00 to 2:00 with bug bait and sells for 1,607.
A YouTube guide calls Swordfish and Paddlefish the easiest king fish to target because their hours and seasons are the most permissive, and recommends the epic rod (or at least gold) plus the Rare Bites ability to boost rare catches during the day.
What you need
A golden rod is the minimum for king fish, and the expert angler quest requires catching two king fish, with guides suggesting Swordfish and Paddlefish for convenience. The ocean species sit at Celestwave, Coral Sea, and Luminwave, reachable by taking or hiring a boat, and each region offers one king species, so fishing elsewhere does not substitute.
Fishing drains stamina, so guides recommend bringing food and lots of bait. The Hooked on Fate ability (level 3 of the Senior Angler tree) removes the need for fish shadows when ocean fishing. On average, one guide reports around 100 catches to land the two king fish it needed for the quest, and king fish appear only at specific hours and seasons.
Source notes
Fish data here is drawn from Eurogamer's fish location list, TechRaptor's fishing guide, Neoseeker's fishing page, and two YouTube king-fish videos. The king-fish count and a few prices differ slightly between sources, and the seven-versus-six discrepancy is reported explicitly rather than resolved. King fish can also be bred in a fish pond for income, as one video demonstrates with swordfish selling for 826 coins each.
