Golden Semilarvatus Butterflyfish (Chaetodon semilarvatus)


The Golden Semilarvatus Butterflyfish, otherwise known as the Red-lined Butterflyfish or the Golden Butterflyfish, are yellow bodied with vertical, orange stripes along the sides of their mid-section. Behind their eyes, they have a dark gray-black patch, and their peduncle dorsal fins smooth into a rounded curve as it nears the caudal area.


It is best to keep the Golden Semilarvatus in a 125 gallon tank or larger with live rock, room for swimming, and plenty of hiding places. These fish can be kept in reef aquariums but with caution. They tend to nip at soft and stony corals (sessile invertebrates) and clam mantles. The Golden Semilarvatus is a rather peaceful breed of butterflyfish and can be kept in pairs or in small schools.



The diet of the Golden Semilarvatus should include: fresh clams, mysis shrimp, marine algae, spirulina, frozen preparations, and herbivore preparations.
