    • Compatible with other fast and semi-aggressive fish.
    • Avoid keeping them with long-finned or slow-moving species.

  10. Breeding:

    • Breeding Rainbow Sharks in captivity is rare.
    • Provide ample hiding spots if attempting to breed.

  11. Health Monitoring:

    • Regularly observe for signs of stress, disease, or changes in behavior.
