4. Filtration and Water Flow:

   • Use a moderate filter to ensure proper water circulation, but avoid strong currents that may stress the fish.

5. Diet:

   • Avoid keeping them with aggressive or fin-nipping species to prevent stress and injuries.

7. Behavior and Compatibility:

   • Swordtails are active swimmers and may display some territorial behavior, especially among males. Provide ample space and maintain a proper sex ratio to reduce aggression.
   • They are compatible with a variety of community fish, but monitor their interactions to ensure a harmonious tank environment.
