Arkaneo is a giant sailfish that occasionally spawns as a random event at the Deep Sea Fishing hub. She swims around for approximately 50 seconds and grants all fishing boosts after departing.
The back portion of her dorsal fin has been removed from her, and attached to Tavia's fishing rod by Tavia during a catching attempt.
- Arkaneo is described in Tavia's Fishing Notes as female; however, Misty refers to Arkaneo as male.
- The fishing boosts granted by Arkaneo last for 15 minutes
