Tropical food fish can refer to two species of fish, the WRASSE and the tilapia. The WRASSE is a type of marine fish found in tropical and subtropical waters around the world. It has a wide variety of colors and sizes, ranging from small, colorful reef dwellers to large, predatory species. The tilapia is a freshwater fish native to Africa, but it has been introduced to many other parts of the world. It is an important food source in many countries, and is farmed extensively for its edible flesh.
