Breeding Swordtails and Raising
Fry (Opens a new browser window for

"Wag Swordtails" are hybrid crosses with Platy. There are many natural and native color forms due to the very extensive natural habitats. For green swordtail, the ground color is olive gray; scale rows along the middle of the body are green to blue; belly is white and there is a light red, dark red or brown longitudinal line on the flanks in all populations (regional forms). In a few variants, there can be one or two additional lines above and one or two below this line. In almost all populations, the dorsal fin has spots or flecks of red. This coloration can also appear in the caudal fin. The sword of males is bright yellow and edged more broadly in black below than above. Old fish (3 to 4 years old) can have a totally black sword from the caudal fin all the way to the tip of the sword.
