Piraniant can currently only be caught in one location, the Sea-Queen's Aquarium by fishing. However fished up Tems do not count towards the total for the "Defeat X untamed Tems" weekly quests. They only count towards the "Defeat X untamed Tems encountered while fishing" weekly quests. So despite having fished up and defeated quite a few Piraniants I am still at 0/25 on my "Defeat 25 untamed Piraniant" quest. As it stands this quest is currently impossible to complete, any help would be appreciated.
