I know that this year's unseasonably warm temperatures have caused the extended survival period for tilapia here in texas, but recent threads on the forum have me thinking about adding them to my pond this spring. I understand that they take to pellets well, so that would equate to a higher feed bill, and I'm okay with that. I'd be stocking them mainly for weed control to make it easier for the greenies to get a meal, but the added bonus of millions of young tilapia swimming around for forage would be great. What drawbacks besides decreased predation of YOY GSF exist if I add tilapia to the pond?
