   • Supplement their diet with live or frozen foods like daphnia, brine shrimp, and micro worms to provide essential nutrients and mimic their natural diet.

6. Tank mates:

   • Threadfin Rainbowfish are peaceful schooling fish and should be kept in groups of at least six individuals to prevent stress and encourage their natural behaviors.
   • They are compatible with other peaceful community fish such as other small rainbowfish species, tetras, and peaceful rasboras.

7. Behavior and Compatibility:

   • Threadfin Rainbowfish are peaceful and active swimmers, often displaying interesting behaviors in a well-decorated tank.
   • They may be intimidated by larger or more aggressive tank mates, so avoid housing them with fin-nipping or territorial fish.
