Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Novelty Catch?

I would like some opinions on this one. It intriques me to add 1 fish of a species I don't want to have or can't sustain in my pond but might someday be cool to catch.

How bad an idea is this if you are careful?

For example I have stocked one of each of these at a size they will not be somebody's snack:

Drum
walleye
google eye

and would like to add a crappie and maybe a flathead
