Origin
Native populations of Xiphophorus hellerii are found in Central America—particularly Mexico, Honduras, and Guatemala. The Tiger strain is a cultivated variant developed through selective breeding.

Visual & Behavioral Appeal
Features intense coloration with tiger-like striping, shimmering body scales, and an elongated tail fin in males that resembles a sword. Constantly active, especially in the upper and mid-water column.

Purpose
Adds motion, color, and contrast to community tanks. Excellent dither fish and natural surface-level foragers. Their bold look also complements high-energy scapes.

Importance
Popular among beginners for their adaptability and livebearing behavior. The Tiger strain is favored for visual flair and fast breeding, making it ideal for both display and educational setups.

Included Resources
Needs moderate flow, open swim space, and some plant cover for rest and fry protection. Sponge or HOB filtration recommended for stable water quality.

Best Use Cases
Works well in livebearer-themed tanks, peaceful community setups, and planted aquariums with strong visual layouts. Great for teaching fishkeeping basics or breeding practices.

Conservation Context
Selective breeding eliminates pressure on wild populations. Wild forms, however, are under some habitat threat—captive breeding helps divert demand.
