   • Offer a balanced diet with occasional treats like bloodworms, brine shrimp, and vegetable matter.

6. Tank mates:

   • Compatible tank mates include small tetras, rasboras, livebearers, and peaceful bottom-dwellers.

7. Behavior and Compatibility:

   • American Flagfish are known for their colorful appearance and interesting behavior.
   • They can be aggressive towards each other, especially males, so it's important to provide plenty of hiding spots and break lines of sight with decorations and plants.
