Lamarck's Angelfish (Genicanthus lamarck)
The Lamarck’s Angelfish or Lamark Angelfish are a type of angelfish that’s sexually dimorphic. Female and male Lamarck Angelfish have silver-gray bodies with horizontal black stripes from the eyes to the caudal fins. They also have long, black dorsal fins.
Some of the main differences between male and female Lamarck’s Angelfish is the markings. Female Lamarck’s stripes, which extend, covering the caudal fin, are bolder than male stripes. Also, the female caudal fin is freckled with black, while the male caudal fin is not.
Recommended housing, it is best to keep the Lamarck’s Angelfish in a 125 gallon tank or larger with live rock for grazing and hiding. These angelfish are known for chasing planktivores such as Fire Gobies, Flasher Wrasses, Anthias, and Fairy Wrasses, but they usually ignore other fish including other angels. Although they are fine with other angels, only one male Lamarack’s Angelfish should be kept per tank due to territorial habits.
The diet of the Lamarck’s Angelfish should include: meaty items such as mysis and frozen shrimp, high-quality angelfish preparations, spirulina, and marine algae. The Lamarck’s Angelfish should be fed at least three times a day.
