Minimum Tank Size: 125 gallons
The Lamarck's Angelfish, also known as the Freckletail Lyretail Angelfish, is a unique member of the angelfish family due to its sexual dimorphism. Both males and females are silvery-gray with horizontal black stripes from eye to caudal fin. However, the female's stripes are bolder, with one extending into and covering the length of the caudal fin. Both sexes have a black, long dorsal fin, but it is larger in females, and their caudal fins are freckled with black.
Compared to other angelfish, the Lamarck's Angelfish is relatively easy to care for, but it still requires a well-maintained tank of at least 125 gallons. They may chase small, docile planktivores such as Anthias, Fairy Wrasses, Flasher Wrasses, and Fire Gobies, but they generally ignore other fish, including other Angels. Only one male Lamarck's Angelfish should be kept per tank.
The Lamarck's Angelfish should be fed a diet consisting of Spirulina, marine algae, high-quality angelfish preparations, and mysis or frozen shrimp. It's worth noting that the Genicanthus genus is the only zooplanktivorous angelfish.
