The Pineapple Swordtail (Xiphophorus helleri) is a popular and visually striking freshwater fish from Central America, celebrated for its glowing orange-and-yellow coloration reminiscent of pineapple hues. With its elegant “sword” tail extension, it makes an excellent centerpiece for community aquariums.

Behavior and Temperament

Pineapple Swordtails are peaceful, active swimmers that enjoy open spaces and gentle water flow. They coexist well with other calm fish such as mollies, platies, tetras, guppies, and corydoras. Males may occasionally show mild territorial behavior, especially when multiple males are kept in a small tank — providing adequate space and hiding spots helps minimize this.

Care Requirements

These fish are hardy and adaptable, making them an excellent choice for beginners. They thrive in moderately hard, alkaline water. Regular water changes (20–30% weekly) and stable temperature maintenance promote vibrant coloration and longevity.

Tank Setup Tips:

• Provide at least 20 gallons per group.

• Include live plants like Java fern, Anubias, or Vallisneria for natural cover.

• Use a gentle filter with good water movement.

• Add floating plants for fry protection if breeding.

Feeding

As omnivores, Pineapple Swordtails accept a wide range of foods. Offer high-quality flake or pellet foods supplemented with live or frozen treats such as brine shrimp, daphnia, and bloodworms. Include spirulina or blanched vegetables for optimal color and health.

Breeding Information

Swordtails are livebearers, meaning females give birth to free-swimming fry rather than laying eggs. Breeding is straightforward — maintain clean water, provide plant cover, and separate fry from adults to prevent predation.
