| − | The '''Swordtail''' (''Xiphophorus helleri'') is a popular [[List of freshwater aquarium fish species|freshwater aquarium fish species]]. It is a member of the [[Poecilidae]] family and is therefore [[live-bearing aquarium fish|live-bearing]]. It is closely related to the [[Xiphophorus maculatus|Platy]] (''Xiphophorus maculatus'') and can interbreed with it. Originally from [[South America]], it has been bred into various hybrid forms for the aquarium hobby due to their hardiness and for being well suited to a community [[aquarium]].
| + | Habitat: Coastal brackish and marine waters of Mexico. |
