Re: Every time I fish for carp...
Ditto what Chuck S said. Nose down/tail up--yup that's your prime target--a money fish for sure. Slow cruisers and shoppers are also very good targets.
Their behavior is heavily influenced by water temperature. Carp are more skittish than Bass but they will most definitely take a fly. Unless it is warmer in CO than here in WA it is still kind of early to be fishing for them. If you are seeing fish though, it will be time soon.
The first few times a Carp takes your fly you'll be hooked harder than the fish. Stay with it; you can do it.
