The Xiphophorus helleri known also as swordtail is one of the impressive fish among the livebearers. Its tail look like a sword, his native color was metal green but today we can see swordtails in many varieties such as green, orange, yellow and the most common is the red swordtail. It requires 10 gallon tank and up, even though they can handle themselves with other fish don't keep them with tropical fish big enough to eat them, weekly water changes are needed, will appreciate plants as a hiding places in their tank.
