Well. if I was entering a peacock bass tournament tomorrow... I'd bring my fly rod and a bunch of small flys (1/2 to 1 inch size) That's the only thing I got them to bite today... flys.
My "fly rod", a 13'6" Amago, hooked all the fish. But because the Tenkara rod is so light you can't use leaders stronger than 5# test.... my largest PB on the Tenkara today was 2 pounds. Those 3 and 4 pound PB and LMB kept breaking the leader.
It was good fun catching the red devils and bass under a pound.

This is the size fish I was looking for... peacock bass under a pound... but when one of the big guys hit, you could kiss the fly goodbye and start re-rigging.

These little guys are lots of fun... although you have to get them into the boat quickly before one of the larger fish grabs it. (This is a baby peacock bass, not a lure with out the treble hooks).

Well, not every large fish broke my leader.... there was a 4# size largemouth bass that grabbed my "lure that I forgot to put the treble hooks on". When it finally realized it was "hooked"... it jumped and threw the "lure with no treble hooks in it". Since all this took place right beside the boat and in clear water... it was really exciting to watch.
The "lure with no hooks" was released back into the grass, none the worst for it's experience.)
I still can't believe I was able to land this 2 pounder.

Why in the world would a fish with such a big mouth go for so tiny a fly?
