Red-Spotted Polanyi: Best Rods and Conditions
Starting off, the Red-Spotted Polanyi is pretty common. To complete CRIMSON CAVERN BESTIARY in FISCH, you can catch it using almost any rod, but I’d recommend a basic one to save your durability. The best conditions for this guy are during warm weather, clear skies, and in the spring season. Just cast your line and wait—it shouldn’t take long!
Here’s a quick list of tips for this one:
Use a simple rod to avoid wasting higher-tier gear
Fish during warm, clear days in spring
Try near coastal areas or calm waters
Easy peasy! Once you’ve got it, move on to the next.
Catching the Red Crab and Sea Raven
Next up, the Red Crab. This one’s obtained through crab cages, so make sure you have a few placed around. Spam those cages—it might take a few tries, but you’ll get it. As for the Sea Raven, it’s also common and appears in various conditions, but rainy weather seems to boost your chances a bit.
For the Sea Raven:
Common in rainy weather
Can be caught with basic rods
Try fishing during daytime hours
Both are straightforward and won’t take much time.

Viperfish and Japanese Dragon Eel Tips
The Viperfish is another easy catch. Head out during rainy weather, at night, and in the winter season. It’s not too rare, so you should hook one quickly. For the Japanese Dragon Eel, you’ll want foggy weather, also at night, and during winter. A mid-tier rod should do the trick here.
Just be patient and keep trying—these conditions might take a few in-game days to line up!
Vampire Squid and Triple Worm Strategies
The Vampire Squid can be a bit trickier. I used a higher-end rod like the Apollo Serenade to nab this one. It appears in foggy weather, at night, and during winter. Cast your line and wait—it might take a few attempts, but you’ll get it!
As for the Triple Worm, it’s all about those crab cages again. Spam them as much as you can—it’s rare, so luck plays a big part. Using an auto-clicker can help if you’re farming passively.
Colossal Ancient Dragon: Using Sundial Totems
Last but not least, the Colossal Ancient Dragon. This legendary beast requires Sundial Totems to spawn. Place a few totems in your fishing spot and keep using them until the dragon appears. It might take several tries, but once it spawns, reel it in with a powerful rod.
Tips for success:
Use Sundial Totems repeatedly
Equip your best rod for higher catch rates
Be patient—it’s worth the wait!
With these strategies, you’ll COMPLETE CRIMSON CAVERN BESTIARY in FISCH in under ten minutes. Happy fishing, and good luck completing your collection!
