  • A specialized herbivore that relies heavily on coral polyps for nutrition.
  • Prefers perching on live corals, maintaining a symbiotic relationship with reef ecosystems.
  • Often observed displaying territorial behavior towards similar fish.

Feeding

  • Strict diet of live coral polyps, making it challenging to keep in captivity.
  • Rarely adapts to artificial foods, limiting its survival in aquariums.
  • Best suited for advanced reef tanks with a sustainable coral population.
  • Supplementary feeding methods are largely unsuccessful due to its dietary specialization.
  • Reef aquarists must ensure a stable supply of coral for proper nourishment.

Habitat
