Clownfish behavior

[Lugmos12]

Add two tiny percula clowns to my tank last night. One is a little bigger than the other. The little one shakes sometimes when the bigger one gets near. They do not fight or nip at each other. They have spent most of the time in the tank swimming around and over the water pump. They do swim out occasionally to the rest of the tank. However is how they are swimming in the video below normal? is this hosting behavior? i heard they can host aquarium equipment sometimes. I also think that maybe the water pump is too much considering that the fish are about 1" to 1.25" inch in size. Thoughts?

 

My water params are good. I fed them 1x today and they ate fine.

Clowns have odd behaviour and swim oddly.

 

The shaking/shimmy is the one clown submitting to the other 

 

I don't see anything odd eith their swimming.

When the flow is on, they tend to bob.
