Australian fish

[George]

For butterfly, Chelmon marginalis is your best bet. This is the Australian version of Chelmon rostratus (copperband). It's as reef safe as copperband.
For angelfish, I don't see many Australian angelfish coming into Canada, other than Chaetodontoplus meredithi and Chaetodontoplus duboulay (scribbled).
Australia has more fish than that but because of high cost of collection, holding and transportation, we don't see them that often, not in Canada at least.
