some fish from a trip to the Camaiú river, 1 1/2 hour flight from Manaus.
These are river fish, damn strong!!
Several times, the small 4 lbs fish caught the fly, and HUGE fish appeared under it, 15 lbs + just taking a look "what is going on here"... the small ones many times played too...
A little different shellback, to improve durability; wrapping it with the rib would work, too.

thread - Danville 6/0 black
tail/shellback - mallard flank dyed woodduck
rib - small wire copper
