I thought about kribs, but they look a little too much like rams, I want to get a few unique fish to add to my tank. I like the look of festivum cichlids as well. I have a pretty narrow band of what cichlids I can put in. I need a peaceful fish, semi-aggressive at most. My PH is at about 7, water hardness is 8 (IIRC), and I want to put fluorite rich gravel in the tank for my plants. So that rules out most of the large, aggressive, alkaline loving, and or digging cichlids.
I have a very good fish store, so I think the quality of their angels will be above par. I asked my fish store, and they said that even "small" angels can grow very large, in a 45-gallon tank; will their growth be stifled? I've heard people agree and disagree with the old "a fish will only grow as large as its environment will support" theory.
How long does it take for an angel to reach full size? I had some small angels as a kid. They didn't last more than a year because of my amateur fish skills, but when they died, they were still about the size of a 50 cent piece. I think I had four of them in a 10 gallon with some neon tetras. I know I was horrible, but I was also eight at the time.
The tank I am getting is a hex tank, so it'll be pretty tall.
