With 4 recognised species, the “pyramid” butterflies are native to the Indian and Pacific oceans. This genus is slightly atypical of the wider family as they are plankton feeders that occur in large schools off reef faces and slopes, subject to strong currents. They aren’t as delicate as many of the other butterflyfishes and can be adapted to captive care, even being kept in groups. Growing to a maximum of around 18cm, they require a resaonably large aquarium with excellent water conditions and frequent feeding. Gnerally, only 2 species are collected for the ornamental market… H. polylepis and H. zoster. Click or touch a thumbnail image for species level information.
