Place the tilapia in a medium bowl and mix with the orange, lemon and lime juices. Cover with plastic wrap and refrigerate for at least 20 minutes or up to 1 hour. Drain the tilapia, discarding the marinade, and pat it dry with paper towels. Place it in a clean bowl, and if not serving immediately, cover with plastic wrap and refrigerate until you’re ready to serve or up to 1 hour. Just before serving, stir in the soy sauce, rice vinegar, onions, mangos, jalapeÃ±os and cilantro into the tilapia. Toss to coat and serve immediately.
