My favorite of the Genicanthus. Pick is of my female. Avarage Female size 5.5" avg Male 6.25" Once acclimated to tank life a great fish with really nice colors. Because they come from deeper waters the can have air bladder issues which make them one of the more expensive genicanthus angles. They are protogynous hermaphrodites which means they are born females and can if needed switch to males. Male are hard to come by in the trade so if you want a pair try two or more females. They tend to live in harems in the wild consisting of one male and two or more females.
