Sometimes I prefer to use the term "selective" instead of "smart". A fish's intelligence is probably a measure of many of factors than just it's tendency to be selective.

I agree that a fish could be selective to a fault. At some point, that moments hesitation means you don't get fed.

The ultimate pond would be to have it full of fish with ample forage, but the tendency to be less selective. I'm working on that right now, without a lot of success. The one exception is my bluegill that I'm selecting for rapid growth. They're not particularly selective right now, even when they're full. That's good......I think.

Holding a redear sunfish is like running with scissors.
