These fish are characterized by their striking red colouration and elongated sword-like tail fin on males, while females have a more rounded fin. They have a slender body with a slightly flattened shape and can exhibit various shades of red, orange, and black. Red Swordtails are peaceful and active swimmers, adding beauty and movement to any community aquarium.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
These fish are generally peaceful and social, making them suitable for community tanks. Males can be territorial towards each other, especially when vying for female attention. They are active swimmers and enjoy exploring their environment. Red Swordtails are livebearers, meaning they give birth to live young rather than laying eggs.
Tank planning
Maintaining stable water parameters is crucial for the health of Red Swordtails. They prefer water temperatures between 22-26°C and a pH range of 7.0-8.0. Provide a well-planted aquarium with open swimming spaces. Regular water changes and filtration are essential to keep the water quality high. Ensure a balanced diet to promote their overall health and colouration.
