The latest Fisch update brought a little surprise for players with a new rarity type. There are a few Secret Fish so far, but the developer could add more in the future. There are ways to make it easier to catch them, but you’ll need a lot of Luck.
All Secret Fish and how to catch them in Fisch

There are multiple Secret Fish in Fisch, but all of them are hard to obtain if you don’t follow their location or requirements. Some are available in rainy weather, so you’ll need to use Rain Totem to speed up the process. Since their catch rate is low due to their rarity, you’ll also need a rod that increases your Luck.
We recommend using only the best rods available, such as the Rod of the Depths (130 percent Luck), Trident Rod (150 percent Luck), Sunken Rod (150 percent Luck), Rod of the Exalted One (170 percent Luck), and Destiny Rod (250 percent Luck) to increase your chances of catching all the Secret Fish quicker.
Since you need to catch them in a specific season, you should use a Sundial Totem to cycle through the days faster.
Here are all the Secret Fish in Fisch and everything you need to know about them:
Secret Fish | Location | Preferred bait | Preferred weather or time of the day | Preferred season |
---|---|---|---|---|
Mustard | Ocean | Seaweed | Rain | Summer |
Long Pike | Ocean | Insect | Rain | Spring and Autumn |
Banana | Ancient Isles (pond or waterfall) | Any | Rain | Summer |
Resin | Get the quest from the Mermaid in Grand Reef to start fishing Resin in the Mushgrove Swamp island. | Any | Any | Any |
Ancient Kraken | Kraken Pool, Atlantis (Once the normal Kraken randomly spawns in the pool, use the Poseidon Wraith Totem to make it Ancient.) | Truffle Worm | Night | Any |
Ancient Orca | Orca Migration (The location keeps changing according to the moving school of orcas.) | Shark Head | Any | Any |
Supercharged Lovestorm Eel | Spawns during the Lovestorm event near Roslit. You have a small chance of catching it. | Chocolate Bait | Any | Any |
Magma Leviathan | In the fishing area of the first stage of the Mariana Veil: Volcanic Vents. | Truffle Worm | Foggy | Summer |
Frozen Leviathan | In the Challenger’s Deep fishing spot. | Truffle Worm | Clear, Night | Winter |
Crowned Anglerfish | Abyssal Zenith: Third level of the Mariana Veil. | Truffle Worm | Foggy, Night | Autumn |
Crystallized Seadragon | Calm Zone fishing spot. | Shark Head | Windy | Spring |
Scylla | After reaching the last stage of Mariana Veil, you have to defeat Scylla. After you defeat the boss by getting the items, you have to wait for the Scylla event and then catch it with your fishing rod. | Shark Head | Any | Any |
Moby | Unlike the Orca migration, the Moby has a five percent chance of spawning in any of the locations during the Whale Migration event. | Squid | Any | Summer |
You can spend a lot of Robux to sell the fish from your inventory without going after a vendor to save time, and the same goes if you want to have the fish appraised before selling them. Catching the Secret Fish will take a lot of time without spending Robux. You can also buy double the Luck for a limited time, making things easier, but you would need to buy enough for at least an hour to be worth it. You can also visit the Merlin NPC in Sunstone Island to boost your Luck.
If you don’t want to spend any Robux catching all Secret Fish in Fisch, it might take days to find them all. You can use this as an opportunity to go after the best rods to increase your chances of completing your bestiary.
Once you catch any of these Secret Fish, you can go toward the Appraiser in Moosewood and start spending some money to get the shiny variant, which comes with a unique sound and appearance compared to regular Secret Fish, making them rarer. Once you have the rare Secret Fish in your inventory, you can use it to get good trades done with other players.
Among the Secret Fish, the Ancient Kraken has the highest value, and it’s probably the easiest to get as well, as long as you are alone in the Kraken pool. You can use the Reisin to get a Water Bubble from the Mermaid, which will let you stay in the water for an indefinite time, which is great for solving underwater time-consuming puzzles in Fisch. The other Secret Fish, like Crowned Anglerfish and the two Leviathan that got added in the Mariana Veil update are used to open the door to go to the final zone where you can fight Scylla’s boss and get the final secret fish in the game.
