Need a hand to complete the Blue Moon bestiary in Fisch? You’re in the right spot! This rare, limited-time phenomenon unlocks two hidden fishing pools, each packed with some pretty gnarly event-only fish. Among them is the highly coveted Moon Idol and its powerful Moon-Kissed buff.
To reel in every species, you’ll need the right bait, perfect weather, and a bit of luck (or a Blue Moon Totem if you’re impatient). But why rely on chance? This guide will explain how to complete the Sea 1 and Sea 2 Blue Moon bestiaries in Fisch.
How To Complete The Blue Moon Bestiary In Fisch
When a Blue Moon event is active—either naturally or with a totem—it will unlock two hidden fishing pools: one in Snowcap Island (First Sea) and another in Lushgrove (Second Sea). These pools only open during Clear Winter Nights and offer your only shot at catching some of the rarest fish in Fisch.
The tables below break down the best bait and weather conditions needed to complete each bestiary. All of the fish species have a higher chance of being caught at Night in Winter.

| Species | Bait | Weather |
|---|---|---|
| Moon Arctic Char | Insect | Clear |
| Silver Scuttler | Bagel | Windy |
| Frost Ray | Worm | Windy |
| Pale Ghost Lumpfish | Flakes | Foggy |
| Blue Langanose | Seaweed | Clear |
| Starbellied Wolf Fish | Minnow | Rain |
| Icy Daggerfish | Truffle Worm | Foggy |
| Lunar Monkfish | Shark Head | Windy |
| Moon Idol Sea 1 (Secret) | Any | Any |
Fisch Blue Moon Bestiary: Sea 2

Note: Only non-secret fish count toward your bestiary progress. Remember that you can buy a Blue Moon Totem at Lushgrove for 500,000 E$ to manually trigger a Blue Moon event. Just make sure it’s a Clear Night in Winter before you activate it, or it won’t work!
