Do you have any thoughts on adding a single angel? I don't want for the fish to ultimately become lonely.
I have a single Angel in my 55 with a Gold Ram and some Rummies at the moment. Mine seems content. He (I don't actually know the sex) interacts with the other fish and is friendly to me... will eat from my hand and swims to the surface when ever I am around. Up to this point I have observed no abnormal behavior from him.
