The most important rule of storing tilapia is that the fish can't be refrozen once it has thawed. Doing so changes the texture and flavor if the fish, making it unpleasant for consumption. You can freeze the tilapia once it is cooked, but it can only be unthawed once after that. Thaw the fish in the refrigerator by placing it in there for 24 hours. Don't thaw the tilapia by leaving it at room temperature. This will cause the fish to go bad.
