Couple of Clown fish questions

[arash53]

Hi,

I just bought a pair of true percula clown fishes form a breeder in Sea-Max he told me they are 6 month.

They hosted in my elegance coral ! I have two BTA one rose and one green but they host in elegance

Here are my questions :

1- They are about same size and they dont fight will they get pair when they grow up or they will kill each other because they are same size?

2- Is it possible to rehost in my BTA or once they host in something they will stay there for ever?

Thanks.
