Mine I added with the coral beauty and they are not the dominant fish in the tank so they are really not aggressive yet and get along well. Even hideout together. But I added them at the same time. I wasn't going to do the flame angel because I had a flame hawk so my red fish was covered but had him for a couple months and didn't see him not one time. Then one day there he was on top of the rocks so I reached in with the net he swam right in so I traded him in on the dwarf angels.
