  • Providing sponge-based food enhances long-term health and coloration.
  • Multiple feedings per day help support its high energy levels.
  • A well-balanced diet ensures strong immunity and vibrant colors.

Habitat

  • Commonly found in reef environments with rock crevices and caves for shelter.
  • Prefers stable water conditions with moderate to strong water movement.
