4. Filtration and Water Flow:

5. Diet:

   • Montezuma Swordtails are omnivores, and their diet should include high-quality flake or pellet food as a staple.
   • Include live or frozen foods like brine shrimp, daphnia, and bloodworms to provide variety and essential nutrients.

6. Tank mates:

   • Avoid housing them with fin-nipping or aggressive fish to prevent stress and injuries.

7. Behavior and Compatibility:

   • Montezuma Swordtails are active swimmers, and males may display territorial behavior. Keep them in a ratio of females to males to reduce aggression.
   • They generally coexist well with other community fish but monitor for signs of aggression and adjust stocking if necessary.
