Can guppies and swordtail fish live together?

Guppies and swordtail fish are both livebearer fish species that are popular choices for aquarium hobbyists. They are generally peaceful fish and can live together in the same aquarium, provided that certain conditions are met.

Water parameters: Guppies and swordtail fish prefer warm water, with a temperature range of 75-82°F. The pH of the water should be between 7.0 and 8.0. Both species also require a moderate amount of hardness in the water, with a dKH of 8-12 being ideal.

Tank size: Guppies and swordtail fish are both active swimmers and need a tank that is large enough to provide them with plenty of space to move around. A tank of at least 20 gallons is recommended for a small group of guppies and swordtails, and a larger tank is recommended if you plan to keep a larger number of fish.

Plants and decorations: Guppies and swordtail fish appreciate having plants and decorations in their aquarium to provide them with hiding places and to help them feel secure. Live plants are a good choice for these fish, as they can help to provide oxygen and remove toxins from the water.

Food: Guppies and swordtail fish are both omnivorous fish and will eat a variety of foods. They can be fed a commercial flake food, as well as live or frozen foods such as brine shrimp, daphnia, and bloodworms.

Compatibility: Guppies and swordtail fish are generally peaceful fish and can live together in the same aquarium. However, it is important to note that swordtail fish are larger and more aggressive than guppies, and they may occasionally chase or nip at the guppies. To avoid this, it is important to keep the swordtails well-fed and to provide them with plenty of space to swim around.

Overall, guppies and swordtail fish can make good tankmates for each other, provided that certain conditions are met. By providing these fish with the proper environment and care, you can help them to thrive and enjoy a long and healthy life.
