Getting There

The Ancient Ruins are the deepest biome of the mines and the source of Mistril Ore, so the Coelacanth is a mid-to-late-game catch. If you're not that deep yet, the mines guide walks through every biome and the fastest way to descend. Once you're on a ruins fishing floor, cast with Rare Fish Bait and be patient — it's a rare spawn even with the right setup.

What It's Used For

  • Museum: Fish Wing, Ruins set — one of the entries you'll need for completion.
  • Quests: Terithia's Request asks for a Coelacanth, and it counts for the Crown Request "Fish".
  • Gifting: careful — it is Disliked by Hayden and Vera. Sell or donate instead.

For every other fish's price, location and season, the full fish list has the complete table — and if you're optimizing Tesserae per cast, the top of that list is where to look.

FAQ

Where do you catch the Coelacanth in Fields of Mistria?

In The Ancient Ruins - the deepest mine biome (ruins floors are around 81-99 on the mines guide). It bites in every season and any weather. Treat floor-5 style labels as biome markers, not elevator level 5.

How do you make the Coelacanth spawn?

Use Rare Fish Bait before casting. It stays a rare spawn even then, so bring patience along with the bait.

What is the Coelacanth worth?

It sells for 140t, but donating often matters more: the museum's Fish Wing Ruins set needs one, Terithia's Request asks for one, and it counts toward the Crown Request "Fish".

Can you gift a Coelacanth?

You can, but Hayden and Vera both dislike it. Sell it or donate it to the museum instead.
