Coral Beauty fighiting - Please Advice

Angels are funny sometimes I have 4 now a bi color asfur imporator and French I got them when they were about 1" now there about 3" to 4" still fight every once in awhile added them at different times in a 60 gal I'm setting up a 150 now for the 3 bigger ones then down the road move up to a bigger tank I've had other times I could get them to live together in other tanks just make sure the all have there own place to feel safe and eat
