Fisch FischFright 3 Bestiary (October 2026) All 44 Fish & How to Catch Them

The Fisch FischFright 3 bestiary adds 44 limited-time Halloween catches to Roblox Fisch, and every one of them lives in the table below with its exact bait, weather and time requirements.

Since it went live on October 17, 2026, I’ve been grinding non-stop, and the short version is: most fish are caught by regular fishing in Autumn on the Caustic Hallow island, a handful get boosted odds in the Grim, Doomed and Vile Frightful Pools, and the rarest entries — Ghoul Nessie, Zombie Nessie and Plush Nessie — need the Haunted Cemetery event or lucky Trick or Treating. Here’s everything you need to finish the list before the event ends.

How to Get to the FischFright 3 Island?

Getting there takes under a minute. Head to Moosewood Dock, find Captain Jack aboard the Haunted Ship, and pick the “I want to Travel” dialogue option. You’ll drop straight onto the Caustic Hallow, where almost all 44 catches swim. While you’re there, knock on doors for Treats (the event currency), complete Goblin objectives for Beatrix’s Cauldron, and stock up on candy bait — you’ll need plenty.

All FischFright 3 Fish and How to Catch Them?

Every entry below spawns in Autumn — that’s why there’s no season column. Bait is a preference, not a requirement, but the listed time of day is mandatory. “Pool boost” means increased odds in that Frightful Pool, and “T&T” means Trick or Treat.?

The Rarest Catches: Jack-o-Moon, Frightful Pools and the Nessies

The hardest entries share one gatekeeper: Jack-o-Moon weather. It can appear naturally at night, but I wouldn’t wait — buy the Jack-o-Moon Totem from the Flying Dutchman merchant for 15,000 Treats and summon it on demand. It grants 9x Luck plus boosts to the Jack-o’, Doomed, Grim, Vile and Eldritch mutations.

Use a Frightful Pool Totem (3,000 Treats) to spawn the pool your missing fish needs. As for the Nessies, both Ghoul and Zombie spawn during the Haunted Cemetery event under Jack-o-Moon at night — Zombie Nessie has Extreme resilience and -90% progress speed, so bring your best rod (the Castbound Rod is a solid pick) and patience. Plush Nessie is pure Trick or Treat RNG.

How Trick or Treating Works in FischFright 3

Trick or Treating is the event’s side hustle, not its main course. Equip the Candy Bucket from your inventory into the taskbar, walk up to any house on the Caustic Hallow, and knock.

When the NPC answers, pick “Treat” to receive Treats or, if you’re lucky, a bestiary fish. Each house starts an 8-minute cooldown after a successful visit, and a fish is never guaranteed — I’ve gone five doors in a row with nothing but candy. Do it between fishing sessions and treat every fish that drops as a bonus.

Pro Tips to Finish the Bestiary Fast

Batch your catches instead of chasing them one by one. Stock four baits first — Black Licorice, Sour Jelly Candy, Licorice and Taffy Pieces — since they cover over 80% of the list, then fish in weather blocks: Clear for Tombstone Tuna and Jawbreaker Jellyfish, Rain for Franken-Flounder, Foggy for Skeleton Sturgeon, Windy for daytime Sour Patch Salmon.

Sell duplicates to the Frightful Merchant for Treats and reinvest them in totems; my Furnisher guide shows how event income feeds long-term upgrades. Save Jack-o-Moon sessions for nights when only Moon-gated fish are left.

FAQs

How many fish are in the FischFright 3 bestiary?

There are 44 limited-time entries in the 2026 event pool — standard fish, relics, skulls, junk catches like the Wooden Stake, and the three Nessies. The official wiki currently logs 39 of them as traditional fish, with the rest being special catches.

What is the rarest fish in FischFright 3?

Ghoul Nessie and Zombie Nessie, which only spawn during the Haunted Cemetery event under Jack-o-Moon at night. Plush Nessie is arguably harder since it’s an extremely rare Trick or Treat drop with no fishing route.

How do you get Jack-o-Moon weather in Fisch?

Wait for it to occur naturally at night, or buy the Jack-o-Moon Totem from the Dutchman Merchant on the Flying Dutchman for 15,000 Treats and activate it yourself.

Do I need specific bait for FischFright 3 fish?

No. Preferred bait only improves your odds of hooking a specific fish — any rod can catch anything. Time of day is the real requirement, so always match the listed Day or Night window.
