I haven’t tried this fly, but it looked like a nice little fly by Krystian Niemy. It is to be tied on a wet fly hook. Krystian recommends this fly for perch or rainbow trout.
Hook: Hanak 260BL no. 8 (any wet fly hook in a size 8)
Thread: black UNI 8/0
Eyes: silver Twin Eyes
Tail/body: orange marabut
Dubbing: black Hareline Angora Goat
