let me clarify. i did not mean to that Landen should go out and by a coral to torcher it. i honestly don't know about the blue angel but have heard many times of flame angels that are in reef tanks. i also believe that in a tank of that size (150g) adding some bright purple (for example) mushrooms or bright colored zoas would probably work. expecially considering the fact that the angels are not bothering the shrooms that are currently in the tank. jmo. kat
