Choosing The Right Tank
Setting up a tank for platies and swordtails needs careful planning. The tank you choose affects their health and happiness.
Think about space, shape, and light before buying your tank. These factors help create a good home for your fish.
Ideal Tank Size
Platies and swordtails need enough room to swim freely. A larger tank means cleaner water and less stress.
- A minimum of 20 gallons is good for a small group.
- 30 gallons or more is better for many fish.

Tank Shape And Space
Choose a tank shape that fits your space and allows fish to swim comfortably. Wide tanks give more surface area for oxygen.
| Tank Shape | Benefits |
| Rectangular | Good surface area and fits many spaces |
| Square | Compact but less swimming area |
| Tall | Less surface area, harder for fish to swim |
Placement And Lighting
Place the tank where it gets stable temperature and no direct sunlight. Bright light can cause algae growth.
- Keep the tank away from windows and heaters.
- Use aquarium lights for 8-10 hours a day.
- Lighting helps plants grow and fish stay active.
Water Parameters
Setting the right water parameters is key for healthy Platies and Swordtails. Proper water conditions help them thrive and show their best colors.
Careful attention to temperature, pH, hardness, and filtration keeps the tank stable. This reduces stress and disease risks for your fish.
Temperature Range
Platies and Swordtails prefer warm water. Keep the temperature steady between 72°F and 79°F (22°C to 26°C). Avoid sudden changes to prevent stress.
Ph And Hardness Levels
These fish do well in slightly alkaline water. The ideal pH is 7.0 to 8.0. They also like moderately hard water with general hardness (GH) between 10 and 20 dGH.
| Parameter | Ideal Range |
|---|---|

Water Filtration And Aeration
Good filtration keeps water clean and clear. It removes waste and harmful chemicals. Aeration adds oxygen, which fish need to breathe well.
- Use a filter rated for your tank size.
- Perform regular water changes to reduce toxins.
- Ensure the filter flow is gentle to avoid stressing fish.
- Add an air stone or bubbler to improve oxygen levels.
Substrate And Decorations

- pH level: 7.0 to 8.0
- Use live plants or artificial hiding spots
- Feed a varied diet with quality flakes and live foods
Raising Fry Successfully
Move pregnant females to a separate tank to protect fry. Fry need small foods like baby brine shrimp or crushed flakes.
