Yellow Pyramid Butterflyfish

Yellow Pyramid Butterflyfish

Hemitaurichthys polylepis

Identification A distinctive butterfly — a white triangular “pyramid” across the flank set against a dusky head, with a bright yellow dorsal, tail and rear. Forms large midwater shoals on the reef.
Maximum Length about 7″
Origin Indo-Pacific
Minimum Tank Size 125 Gal.
Reef Compatibility Reef safe (with caution)

Behavior

Unusual among butterflies in being a planktivore rather than a polyp-grazer, which makes it one of the few genuinely reef-suitable Chaetodontids. Hardy and active, it is happiest in a shoal hovering in the current.

Diet & Feeding

Planktivore and omnivore. Offer mysis, enriched brine, marine preparations and pellets a few times a day.

Cautions

Generally leaves corals alone, though the odd individual picks — hence the “with caution.” Needs strong flow, open swimming room and ideally a group. A jumper.
