Keoki & Yuko Stender's outstanding Longnose Butterfly (Forcipiger flavissimus) photo.
The Yellow Longnose Butterflyfish behaves in the typical Butterflyfish manner, but is a species that is best kept singly or in larger aquariums as a mated pair. It does better with other non-aggressive fishes, but can be placed into a moderately-aggressive community if introduced into the aquarium first.
