I am going to Alabama to pick up my Tilapia the first week of June. I was thinking of getting 10lbs but the fish man said I need at least 30lbs. These are supose to be big fish 1lb or so. The only preditor fish in the pond so far are 10-12in Hsb. I will also be picking up some F1 bass on the way home with the tilapia but they will be small. I want the tilapia to provide some extra forage, but I really want them to clean up the slimey algae around the pond. What do ya think?
