Nathen, if your goal is to reduce the detritus, do not use predators with the tilapia. Plan on cleaning up a ton or more of dead fish in the cool weather though without predators being in the pond.
I was simply answering your question to me as to if a CC could be a predator of tilapia.
With predators, more tilapia will need to be stocked to meet the same detritus goals, but few dead fish will need to be cleaned up in the late fall.
