Care
Pyramid Butterflyfish are considered moderate to care for. They require a well-established aquarium with plenty of swimming space and a stable environment. These fish are planktivores in the wild, so their diet should consist of a variety of meaty foods and plankton-based preparations to mimic their natural feeding habits.
Reproduction
In the wild, Hemitaurichthys zoster forms large, loose aggregations for spawning. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic and will settle into the reef once they reach the juvenile stage.
Habitat
Pyramid Butterflyfish are found in the Indo-Pacific region, typically in clear lagoon and seaward reefs. They prefer areas with strong water movement and are often observed in groups hovering above the reef, feeding on plankton carried by the currents.
