Sign of submission?

[Cwentz758]

I have three clowns currently ranging from 4” to about 1 1/2” for the most get along great they’ve been together for about 3 years. But I notice they have a tendency to go low in the back and one will like go sideways and shake like it’s having a seizure. Usually it’s the two smaller ones. I’m guessing sign of submission or just clown being clowns?

I always considered it a sign of submission, but I have seen even large established females shimmy.
