[quote=hqgc;486053]I've been noticeing that alot of people keep more then one angel in there tanks and alot of the online fish retailers advise against keeping more than one.
I would like to put a blueface in with my emperor in my new 180 fowlr.
Sorry to have to tell you this but your tank at 180 is simply too small to accommodate one large angel let alone more.
There is an excellent discussion on the needs of angelfish here.

There is a second article in the following addition which sets out the fish that you can keep with an angel.
