I have been trying for several hours and about 6 stacks of Midge larva to catch this singular fish. Does anyone know more about its requirements, ie weather, bait, time, tug type, hookset? Any more info is appreciated. I've tried scouring Google but there's minimal info on this thing right now.
It is a collectable fish and I was gonna try to catch it for that, but now I just want to log it in my journal and move on lol.
