Clownfish loyalty?

[reefd00d]

Is it typical for a clownfish to pick a nem and then that's it's favorite?
I have a clownfish and 3 nems. My clown has picked one nem and never visits the others.

Its not so much loyalty as it is territory. Of course, the symbiotic relationship they form is welll... LOYALTY... also my maroon feeds both her nems.. Clowns form a special bond with their host.
