Overview and how to spawn

The Colossal Ancient Dragon is an Exotic-rarity fish with a base weight rating of 200,000 kgs. Its average base value without factoring in Mutations is around 125,000 C$. With Mutations and higher weight, its value can easily rise well over a million. The best possible conditions to catch it are Clear Weather and the Spring or Summer Season.

Coinciding with the notification, you will see a red marker where the fish will spawn. Use your best fishing rod to try and catch the Colossal Ancient Dragon.
