Fish on Volcanic Island until this species is in the satchel at the required weight. Lock it with the key icon so a sell action cannot take it.
How do you use Ancient Trihorn Fish?
Turn it in only to the unlock NPC that names it. Azure Dragon Soul accepts any Volcanic Legendary, so do not spend a heavy Ancient Trihorn Fish on that race if it meets a Fossil weight gate.
