In this guide, we’ll walk you through where to find the rarest fish on each island in Fisch Roblox. We’ll show you what weather to look for and which bait works best, helping you spend less time searching and more time catching these awesome fish.
Rare Ocean Finds in Fisch Roblox
The ocean is home to some really cool Mythic fish. Keep an eye out for the Colossal Squid, it only shows up on foggy nights in the Deep Ocean. If you’re shark hunting, try catching the Great Hammerhead during windy spring days with Fish Head bait. There’s also the Mythic Fish, which comes out during the day and likes to nibble on Flakes.
Moosewood and Roslit Hot Spots
Over in Moosewood, you can find the Whisker Bill swimming in saltwater. This Mythic fish really likes Truffle Worm bait. At Roslit Bay, try catching the Obsidian Swordfish near the volcano during windy or clear summer days. Just remember to bring some Minnow bait (it’s their favorite).
Snowcap’s Secret Fish
The caves of Snowcap Island hide some great catches. The Glacierfish only comes out during rainy or foggy nights, and you’ll need Truffle Worm bait to catch it. There’s also the Ringle, which you can find in saltwater on clear or foggy nights. This one’s a bit different; it actually prefers Bagels as bait!

Sunstone’s Best Catches
Sunstone Island has both Legendary and Mythic fish swimming around. Look for the Sunfish during clear summer days, or try catching the Wiifish in autumn using Flakes as bait. The Voltfish likes to come out during rainy nights, and Super Flakes work best for this one.
Deep Water Treasures
Some of the coolest fish are in the deeper waters. Check out the Desolate Deep for the Emperor Jellyfish. It shows up in the rain and goes for Magnet bait. There’s also the Sea Mine, but you’ll need a special crab cage to catch this one, and it only appears in clear weather.
Atlantis Fish Guide
Atlantis has different zones with some amazing fish. In the Sunken Depths, try finding the Celestial Koi during rainy winter nights. The Abyssal Goliath hangs out in Poseidon’s Temple at night, and over in the Kraken Pool, you might spot the Void Emperor. Both these fish love Truffle Worm bait.
