Sauk, you desribed the situation perfectly. The Triploids need to be put in selective fisheries and Flyfish only fisheries, otherwise these fish will all be gone within 2 months after planting. In case you didn't know Trips are aslo much more aggressive feeders and can be fished out in no-time at all. Also, if you do decide to release Trips, take extra time reviving them for they recover very poorly. Look for the blunt nose and put 'em back.
