Unfortunately tilapia is as damaging as the Pacu as an invasive species, in some places it has wiped out the local fish population as they breed like rabbits and ravenous eaters!!Anyway tilapia has been bred n farmed intensively in this region, not for eating but mainly for fishing, they grow fast and fight hard and readily take anything: lures, flies, baits, you name it.They are not as ferocious
