Emperor Angel fish
 

Im look to buy a juvenile emperor. Will it get along with my purple tang and long nose butterfly? I also have a few mushrooms and i believe a finger leather. WIll it be fine with the corals? Also how long does it take for the fish to change colour into its adult stage?
thx

not aware of how long to change. I considered it on numerous occaisions for my reef tank.unfortunately listed as highly unlikely to be reef safe. such nice markings though. as a comprimise I ended up buying a coral beauty which is considered hit or miss when it comes to reef compatabillity...no problems with corals yet. The odd pick here and there. no question happy with the colour this fish adds to my tank and seems to be very active

compatible
 

your emperor will be the king of the tank so don't worry about your purple tang. i had a 3.5" juvi emperor who immediately became the king despite the purple and yellow tang complaints.
not too sure about your corals though being compatible with him.
