Picassos are percs; so are snows/Wyoming whites.
You can get any group of clowns to live together when they are very young, even maroons. The problems come in when they get older and mature enough to spawn. Much sooner for maroons lol.
What happens is the female gets territorial, and has a territory she will defend to all comers. And this territory expands as she gets older. She gets more aggressive when she is mature enough to spawn.
Now, the normal reaction of juvenile clowns is to swim away far enough from the female so that her aggression is diffused. in case you did not know, clown families have an adult male, an adult female, and the rest will stay juveniles as long as the male and female are there, if it is 20 years.
Anyway, normally the juvies will swim away. Easy to do in the ocean. In the confines of the tank however, they can't escape her territory and it can go very badly. Her territory can be measured in square feet.
Occs live in family groups, percs don't. So what often happens is that percs live together harmoniously for 15-24 months, then its like a switch gets flipped in the female and she goes after the juvies.
Now, all clowns are individuals and may react differently; this is very common. More common that continued harmony.
Really nice hosts lesson the aggression. So do really big tanks, in which they can swim away far enough.
