Fish Compatibility

I have an Oceanic 58 gallon tank (established community) with the
following inhabitants:

1 Eibli Angelfish (Centropyge sp.) - 2.5 inches

1 Yellow Tang (Zebrasoma flavescens) - 2.5 inches

1 Blue Tang (Paracanthurus hepatus) - 3 inches

1 Teardrop Butterfly (Chaetodon unimaculatus) - 2.5 inches

2 Blue Chromis (Chromis cyanea) - 1.5 inches and 2.5 inches

5 Green Chromis (Chromis caeruleus) - all between 1 and 2 inches

2 Clownfish (Amphiprion ocellaris) - 1 inch and 1.5 inches


All of them get along well and the tank looks great. I run copper in
the system in order to control parasites (because I do not have a
quarantine tank). Also, I have an 8 watt UV on the tank. I use a good
wet-dry and a protein skimmer for biological filtration.

The tank is running great and it looks great.

Now the question...

I would like to add a juvenile angelfish. My preference would be to
add an Emperor angelfish. My thinking would be to find one about the
same size as the Eibli. Or, would you think I should find one a
little larger?

I'm looking for fish I could add with minimal risk for aggression
(either way).

Also, I would be interested in any other suggestions you might have
concerning additional fish.

Thanks, in advance, for your suggestions.
