brad - the fatheads are a waste of money in an established pond with bass already stocked. They are slow swimmers and the bass will wipe them out almost immediately especially in clear water. They can be used to "boost" your spring feed but that is a really expensive snack. The crawfish usually will either become established and multiply or fail totally - not much in between. If you have some rock rip rap or mud shoreline you may have a shot at the crawfish getting established - worth a try though. Tilapia and shad are the only other forage fish I am aware of but they can both have downsides to a pond. Let some of the pros on this site like Bob Lusk advise you further. TK
