I caught a far bigger Israeli Carp many, maybe 20 years ago. If it is an IC, are they reproducing or could they vary in size that much over all these years. They are behaving strangely, milling about near the surface in groups of 3 to maybe 6.
Incidentally, he didn't bite the worm, he was caught with a 16 gauge.
