Platy Fish (Xiphophorus maculatus / variatus / xiphidium)
Platies are live-bearing fish known for their peaceful nature, making them an excellent choice for both beginner and experienced aquarists. They come in a wide variety of colors and fin shapes due to extensive selective breeding.

When referring to “Platies,” this usually includes one of the following three commonly kept species:

• Variable Platy (Xiphophorus variatus)

• Southern Platy (Xiphophorus maculatus)

• Swordtail Platy (Xiphophorus xiphidium)

Because of frequent crossbreeding, identifying the exact species can be difficult, as many aquarium Platies are hybrids with diverse color patterns and shapes.

These fish are very easy to care for and are known for their playful and active behavior, especially when kept in groups. They exhibit engaging social interactions and make a lively addition to any community aquarium.

Temperament: Platies are extremely peaceful and generally get along well with other non-aggressive species. However, they may occasionally nip at long-finned fish, mistaking fins for food. Also, to reduce stress and aggression during breeding, it’s recommended to maintain a male-to-female ratio of 1:2 or 1:3.

Sexing:
Males are typically smaller than females. The key difference lies in the shape of the anal fin:

• Males have a narrow, pointed anal fin (gonopodium).

• Females have a broader, fan-shaped anal fin.
