Overview
Give it at least 340 litres with open water for cruising and some current at 24 to 28 C. It is peaceful and one of the few angels truly safe with corals, so it fits a mixed reef well and can be kept as a male with one or more females. Feed frequent small meals of mysis, enriched brine, and prepared foods to match its planktivorous diet. It picks at sponges and bryozoans but leaves corals and clams alone.
In the wild
The zebra angelfish is a swallowtail angel that hovers in open water above the reef slope picking plankton, unlike the rock-grazing large angels. Males are barred while females are plainer, and the two swim in loose harems. It has long trailing tail lobes that give the swallowtail name. It is calm and coral-safe.
Good to know
Genicanthus caudovittatus reaches about 20 cm and, like all Genicanthus, is a planktivore rather than a sponge or coral feeder. This diet makes the genus the only reliably reef-safe angelfish. Males and females differ in pattern, and females can change into males.
Did you know
Swallowtail angels eat drifting plankton instead of coral, which is why this whole genus is trusted in reef tanks where other angels are not.
