It's a good price on one, but it is a gamble. What size is your tank? Dwarf Angels are a gamble with corals but IMHO you can increase your chances of success by having a well established tank with algae to graze on and daily seaweed/nori feedings. Flame Angels tend to be one of the dwarf angels with higher than average success rates with leaving corals alone (particularly if you follow the guidelines mentioned above). Flame Angels do have another issue and that is that they tend to be one of the more aggressive Dwarf Angels, so if you have smaller more timid fish, they can bully them. I had to remove a Flame Angel due to aggression towards a Purple Firefish, Diamond Watchman Goby, and Scissortail Dartfish. A larger tank can help with the aggression though and that is why I inquired on the size of the tank.
