Flame Angel or Juvi Koran?????

Personally we like the looks of the Koran better, though they do change as they mature. The Flame may or may not be less interested in your coral but any angel runs the risk of nipping at corals. We have a Singapore angel and it leaves our coral alone for the most part. He will pick at one particular group of polyps every now and then and that usually just means "feed me". Alot of things in your tank arent exactly tasteful to any fish, most of the time if they have a good diet and are well fed they wont bother anything. Coral seems to be a last resort of alot of fish who are eather lacking something in their diet or arent fed often enough. Alot of typical stuff that is preached about certain fish eating coral are just theories and not facts. We have had more than our fair share of "coral eating" fish in our reef tank and the vast majority didnt touch a thing, each fish has its own personality but a well balanced diet makes all the difference in the world.
