I've caught yellowtail barracuda, great barracuda, reaper fish, fire fish and holy mackeral. I was thinking that the mountable fish are the truly rare ones that require 120 fishing? Of course that's just a guess, as it seems nobody has any reliable information. I'm still at 100 fishing; 100+ fishing quests and still no fishing PS for me. I will saw that since the change a couple days ago, I have not received any quests for dungeon fish, so I guess that's what they meant when they said 106 for dungeon. Soon hopefully, I like fishing in dungeons.
