Honestly, it's hit and miss, based on the individual. Afraid the only way to find out is try one and see how she behaves. I've known several reef tanks with flame angels that didn't have a problem, but that doesn't guarantee anything. Only reason I don't have a flame myself is that I have a potter's angel and I don't want to risk the potential aggression. The potter's, actually I have had two now, I had one before - a few years ago... has been for me a model reef citizen. I've had her in with SPS and clams and LPS and only ever eats the food I give her.
Here's a picture of my potter's - it's actually not the best photo to show off her exquisite colours- because I was just playing around with the camera one night after lights out and took this picture by accident (she's impossible to capture in a photograph if you actually
try to take a picture of her - because she's a tease - "Hey look at me pose. I'll sit here and wait until you're just about ready to press the button, and then I'll dart off into the rocks.
".) The camera's flash did wash things out a bit, but I fiddled with the colour saturation and balance afterwards and was able to come up with this, which is "sort of" close. Basically the best I'm able to do until the day I actually get lucky and capture her in a photo where I *intended* on photographing her.
