Christmas Leviathan

Admin-Exclusive is the only location listed for the Christmas Leviathan, a Special-rarity fish that belongs to the Fischmas theme. Its entry carries a one-line cheer, "MERRY FISCHMAS!", and little else in the way of lore, so the numbers do the talking.

Weight is the headline: it averages 290,000 kg, with a floor of 200,000 kg and a ceiling of 798,000 kg. That puts its maximum weight 27th among the 663 fish with a recorded top weight. The price per kg is tiny at C$0.148, yet the sheer mass still produces an average sale of about C$42,928, which ranks 43rd of the 742 documented fish. Catching it also pays 20,000 base XP.

In the same zone, Christmas Ancient Megalodon and Colossal Nico share its Special rarity, so expect them to be the other large catches tied to Admin-Exclusive. Because the fish is flagged as obtainable, the practical advice is simple: if you see it, keep it for a big one-off sale or for the XP. Do not waste it on a quest that only needs a small fish; its value comes from weight, not from a high per-kg rate.
