+something on the last posters said.
apart from Geniacanthus, no angel is reef safe.
whoever tells your otherwise, is lying.
they are omnivores and in their diet, corals are included. some nip at them, some eat them others dont touch them.
pretty much like humans and lets say, broccoli.
I can swear that I can find 10 people here that love broccoli, others that can have the occasional bite, other 10 that hate the thing to bits.
Same thing with fish.
Bit hit or miss - Coral Beauty, Flame Angels, etc. Even big angels, although with big angels thing is more of a miss than a hit
I've kept a full grown Asfur angel ( and that's a biggie ) that was a
nipper. I've also kept a full adult ( that I raised from juvenile ) Narvachus ( blue grilled angel ) that was the most behaved model citizen that I ever saw in my life. Reef wise that is.
And I had a friend who bought a Narvachus and ate all its xenia in 10 seconds. I wish at the time mine did the same but he couldnt care less.
Each fish is absolutly different when comes to coral eating, well angels that is.
Take your gamble.
Me for example and after having 250€ in Blastomussas alone, and 300€ in assorted corals ( and I have a tank that is new ), having my heart set on an Australian Scolymia that is on the LFS that has the marvelous 250€ price tag, Im not going to risk on a 30€ fish - and trust me , I love both the Coral Angel and Flame Beauty.
But its not worth if I get one that munch on my corals.
And they can be model citizens for years and one day look at your prized coral and think "wait a second, that seems tasty". others ignore it all their life.
