Green Swordtail
Xiphophorus hellerii
Green swordtails inhabit warm, slow-moving freshwater streams, springs, and vegetated pools. They graze on algae and plant material while also picking off insect larvae and small aquatic invertebrates. Males use their elongated lower tail ray, the sword, in courtship displays and rival encounters.
