Lamarck's Angelfish - Genicanthus lamarck: The Lamarck's Angelfish (or Lamark Angelfish) is also known as the Freckletail Lyretail Angelfish. They have the distinction among angelfish of being sexually dimorphic. Both male and female are a silvery-gray with horizontal black stripes from eye to caudal fin. The female's stripes are bolder with one extending into and covering the length of the caudal fin. In both, the long dorsal fin is black, although larger in the female, and the caudal fin is freckled with black.
Members of the genus Genicanthus are planktivores and will not bother corals or clams in the aquarium, making them the perfect reef angel. Lamarcks' angelfish is white overall, with black lines on the body, black on the dorsal fin and small black spots on the tail. The tail in this species, and other members of this genus, is lyre-shaped, which is indicative of a speedy open water swimmer. It readily adapts to life in captivity, accepting aquarium fare and acclimating to the conditions found in a well-maintained aquarium. Therefore, it is important to provide them with plenty of swimming room. Like all Genicanthis, they tend to be passive toward most other fishes.
Water Conditions: Keep water quality high (SG 1.020 - 1.025, pH 8.1 - 8.4, Temp. 72 - 78° F).
The Lamarcks Angelfish groups Up to 9 inches in size. Dwarf Lamarcks Angelfish Are generally available at 2-3 inches.
The Lamarck's Angelfish is something of a rare fish ranging from the Solomon Islands and New Hebrides northward to Japan.
