Introduction of swordfish species
1. There are many kinds of swordfish, including red sword, black sword, red and white sword and apple sword. These are difficult to raise. Whether it is acidic water or alkaline water, it can survive well even at a low temperature of 20 degrees. Because the male tail has no reproductive ability, the female tail must breed with the male red sword, so the tail sword is not common.

2. Swordfish (Xiphophorushellerii.var), also known as red sword and swordfish, belongs to the order (CYPRINIDAE) and the suborder Cyprinodonta. It is a cultured freshwater ornamental fish and is loved by people because of its red color.
