Lamarck Angel

The Lamarck Angelfish (Genicanthus lamarck) — also known as the Freckletail Lyretail Angelfish or Lamarck's Angelfish — is one of the most unique and reef-aquarium-friendly angelfish in the entire hobby. Unlike most members of the angelfish family, Genicanthus species are open-water plankton feeders rather than grazers, which makes them one of the very few angelfish that are genuinely 100% reef safe with no risk to corals, clams, or sessile inverts of any kind. This species is also remarkable for its pronounced sexual dimorphism — males and females look so different they were originally classified as separate species. Males display a silvery body with four bold black horizontal stripes running the length of the body, a long flowing lyre-shaped tail, and a single bright yellow spot on the forehead. Females share the silvery base color and lyretail but lack the forehead spot and feature a black-edged dorsal fin and tail tips instead. Both sexes are elegant, graceful, and refined swimmer
