Spotbreast Angelfish, Male

(Genicanthus melanospilos (male))

Genicanthus Angelfish should be added to well established aquariums with plenty of room to swim. Plenty of rock work, caves, cracks and crevices should be provided for grazing and hiding. Genicanthus Angelfish are generally considered reef safe. A diet of marine meaty, angel and algae based foods should be provided multiple times daily. Care will need to be taken when handling Angelfish as they have cheeks pines, avoid using nets when handling. Genicanthus Angelfish are hermaphroditic meaning they may have both sex organs at some point in their lives. May keep pairs or harems in the same aquarium but should be added at the same time. Males and females are sexually dimorphic meaning males and females are easily distinguishable.
