Wild is from the ocean, and aquacultured was bred and raised in a tank.
I think it will depend on the type of clown, but most clowns unless a mated pair will want to dominate and will probably pick or kill the other.
As for the damsels it depends on the type as well, but most damsels are very aggressive fish and will dominate the whole tank eventually, if you choose to go with the damsels, they should be the last fish added not the first.
So when you choose your stocking list, take all that in to consideration, it is really important to check compatablitily/aggressiveness before stocking.
