What is Harpoon a Fish?
Harpoon a Fish is a Roblox simulation by FirstTry. You aim a harpoon, fire, and reel sea monsters into an aquarium, then evolve them into the biggest and rarest catches you can find.
Getting fat lets you sink deeper, where new species and real danger show up. You can also steal another player's fish, so only one diver walks away with the trophy. The index lists 1,800+ unique fish.

Codes, the first dive, catch tiers, Mukbang leveling, evolutions, steals, badges, and the current FirstTry events.
Harpoon a Fish Codes
Harpoon a Fish prints its current promo code in the official Roblox description. MONSTER is the only code listed there, and a public beginner video shows it redeeming in-game. No second active code is listed by the developer.
MONSTER+3k XP and +3 Ruby KeysHarpoon a Fish Beginner Guide
The official How To Harpoon lines are the first loop every diver needs. You aim and fire, time the reel, then decide whether to steal or keep the catch. Caught fish go into your aquarium and become a pet you can grow.
Harpoon a Fish Tier List
Named catches are grouped by official Roblox badge award rates, not by an in-game letter rank. The rarest badges sit at 0.3 percent of players. Kraken and the Easy WHAT??? badge are much more common.
MEGALODON, NIGHTCRAWLER, and POSIONED HEXJAW. Each catch badge is awarded to 0.3% of players.
CROCODON. The badge reads You caught a CROCODON! and is awarded to 0.6% of players.
KRAKEN. The badge reads You caught the KRAKEN! and is awarded to 11.4% of players.
WHAT???. Roblox labels this catch badge Easy, and 51.5% of players have it.
Harpoon a Fish Leveling
The official description tells you to get fat and sink deeper for new sea monsters. A public beginner walkthrough shows the Mukbang Table as the way to eat catches and raise stats. Deeper water is also where the game warns that danger shows up.
Harpoon a Fish Evolve
Caught fish become aquarium pets that you grow into bigger, rarer monsters. The New Pet badge marks the first one you keep. The index goal on the official page is 1,800+ unique fish.
Harpoon a Fish Steal
Stealing is a core official rule, not a side mode. You harpoon another player's fish and contest the reel. Servers hold 6 players, and only one diver keeps the trophy.
Harpoon a Fish Badges
These are official progression badges from the Roblox badge list, separate from the rare boss catches. Award rates come from Roblox. Stranded and Monster Hunter are marked Freebie on the game page.
Harpoon a Fish Update
FirstTry is running two official Roblox events on the Harpoon a Fish page. Update 2 is live through October 24, 2026, and a new zone event is scheduled for October 21. Both pages are hosted by the FirstTry group.
