My 2 cents. With the fan coral being the only moving coral, (in or out of rhythmic synchronization), it kinda indirectly emphasizes the fixed non-movment of the other corals like they're just things sitting there, not moving, not breathing not living. Not being anything particular if you catch my drift. Maybe not move the coral fan so much, perhaps more subtle movement? 
...or maybe wait and see how it all looks, with the other things moving the way Jim has planned, before fine-tuning individual features.
