The Pineapple Swordtail, a color variation of the common Swordtail (Xiphophorus hellerii), is a freshwater fish known for its vibrant yellow-orange body with darker orange patches on its back and dorsal fin, resembling a pineapple. Males have the distinctive "sword" extension on their lower tail fin, while females lack this feature. They are peaceful, livebearing fish, well-suited for community tanks.
