Strange Clownfish Behaviour

[JT-Reefer]

Hello,
I am a new reefer and have 2 clowns at the moment with a bicolor blennirs in a 33 gallon tank.
The clowns were getting along well until a few days ago when the smaller began swimming erratically and the larger began attacking the smaller. I was of the impression the larger was female and they were bonded but now I am not sure.
The smaller clown is also not eating at this point and I am unsure what to do.
I put the larger , more aggressive one into a cage and the smaller is still swimming strangely.
Any help would be appreciated!

I can’t watch the video on my phone, but they could have just been mating. The male does a weird twitching thing before they spawn. Do you have enough rock in there with good hiding places? Could be frustrated they can’t find a good spot to lay the clutch.

Sounds like the larger is just establishing dominance.

That does not look good. I suspect a thrashing by the larger clown has done some brain or spinal damage. I would euthanize that fish.
