Urban I am pretty sure its not a cross I in the summer when the carp are all over the surface in the delta I see one or 2 now and then. This is the second one I have cought the other was in the 3lb range I know teh butterfly koi look just like them but more colorful seeing its a closely related fish I would assume its pretty much a long finned carp or butterfly. Anyhow check with you buddies I know you have a way of finding out forsure mabey I cought the record!

I have cought carp upto 35lbs in the delta but that was on tuna gear. I would prefer a 10lber on 4lb anyday.
