Swordtail

Environment

Provide a tank of at least 100 liters, elongated for swimming, planted on the sides with a clear central space. The water should be hard and alkaline (pH 7.0 to 8.3) between 22 and 28 °C. A well-fitted lid is recommended as this jumper can leap out of the water.

Feeding

Omnivorous, the swordtail accepts flakes, pellets, frozen prey (brine shrimp, bloodworms) and plant matter such as spirulina or blanched vegetables. Vary the food to maintain bright colors and good health. Avoid overfeeding.

Health & common diseases

The swordtail is susceptible to ichthyophthirius (white spot), fin rot and fungal infections, especially in cases of stress or poor water quality. Monitor changes in behavior, the appearance of white spots, cottony filaments or frayed fins. Good hygiene (regular water changes, avoiding overcrowding) and stable temperature prevent most diseases. Females can suffer from complications during birth if they are stressed or over-solicited.

Tips & tankmates

Males can be territorial with each other: keep a single male or alternatively a large enough group with several females to dilute aggression. Breeding is very simple and prolific; provide floating plants for the fry. Some dominant females may develop male characteristics.
