   • Keep the water temperature between 24 to 30°C (75 to 86°F).

4. Filtration and Water Flow:

   • Compatible tank mates include larger, robust community fish that can hold their own against the Rainbow Shark's territorial behavior.

7. Behavior and Compatibility:

   • Rainbow Sharks are territorial and may exhibit aggression towards similar or bottom-dwelling species.
   • Provide hiding places and territories to reduce aggression, and consider keeping them singly or in larger tanks with plenty of hiding spots.
