Genicanthus semifasciatus
| Identification | A swallowtail angel with a lyre-shaped tail. Males show an orange-barred body with a yellow head; females are plainer with a dark upper head and back. |
|---|---|
| Maximum Length | 8.3″ |
| Origin | Western Pacific (Japan, Taiwan, Philippines), deeper reefs |
| Minimum Tank Size | 125 Gallon |
| Reef Compatibility | Reef safe. One of the few truly reef-safe angels — a plankton feeder that ignores corals and invertebrates. |
Behavior
Peaceful, active midwater swimmer. Genicanthus angels hover in the open water column picking plankton. Keep singly, as a male-female pair, or one male with several females. Hardy once established.
Diet & Feeding
Frequent small feedings of mysis, enriched brine, finely chopped seafood and prepared angel/plankton foods.
Cautions
A deepwater fish — acclimate slowly to light. Males may bully in cramped quarters.
