If you love fishing all day in Fisch just to find the rarest of them, then the Secret rarity fish must be at the top of your bucket list. Not only can you sell them for a lot of money, but some of these secret fish help you unlock quests or are simply priceless in terms of trading value. If you’re the collector type (like my Editor, who is addicted to collecting Heavenlys), there should be no hesitation for you to hunt them all down. In this guide, we have included every secret fish you can find in Fisch, along with tips to catch them.
Full List of Secret Fish and How to Catch Them in Fisch
After the Lego update, we now have 28 secret fish in Fisch. Given that they carry the Secret rarity, catching them will take a lot of fishing. Getting them without the best Fisch rods is almost impossible. We still say almost, thanks to the RNG aspect of the game.
Nonetheless, we recommend you start hunting the secrets with Ethereal Prism Rod, Poseidon Rod, Heaven’s Rod. Keep in mind that the second sea’s secret fish are no longer available as the second sea is removed from the game. With that said, here is a list of all Secret fish in Fisch and the preferred conditions and bait required to catch them:

Wondering how these amazing Fisch secret fish look when you hold them in your hand? Here is a preview of the latest secret fish, including the Moon Idol Sea 1, Toilet Fish, and Primordial Levi, among others:
One thing you should remember while catching almost every Secret fish is that the progress speed will be almost near -80% or 90%. That is why we recommend using a fishing rod with the Steady or Blessed Song enchant. You can also apply the Hasty or Quality enchant to rods with better resilience.
Remember that most of the Secret fish require some special conditions. That’s why we recommend you keep some totems, such as the Aurora Totem, Sundial Totem, Tempest Totem, and Smokescreen Totem, in your inventory. For some good baits, you can either get Coral Geode, Quality Bait Crate, or redeem Fisch codes that the developer shares from time to time.
Scylla is currently the most valued Secret fish in Fisch. So, I recommend that you not trade this four-headed beast for a lower-value fish or item. To get to it, you must get the Magma Leviathan, Frozen Leviathan, and Crowned Anglerfish first.
If you are struggling with luck, you can go to Sunstone Island and get Merlin’s luck. Moreover, you can boost it even further by popping the Aurora Totem. If you want to spend some Robux, you can go for a server luck boost and help your friends in the process too. This will increase your chances of spotting more Secret fish.
That ends our list of all the Secret fish in Fisch. We will update it as the developers add more fish with Secret rarity in upcoming updates. Have you caught any Secret fish in the game yet? Tell us in the comments below.
