Clown acts like hes getting shocked.

I bought a couple of clownfish a couple of days ago and they are both doing fine. One of them I noticed today starts twitching real bad like he's getting shocked. It doesn't happen often and it's only the one fish. I tested water yesterday.
pH: 8.3
Temp: 79
Salinity: 1.025
Calcium: 440
Nitrate: 20
Nitrite: 0
Phosphate: .025
I also added a long tentacle plate coral at the same time and the clownfish love it. I know these things stings. Is it possible he's just not used to the sting yet.

most likely. They sting the clown and then the clown goes back and forth to it until he's used to it and then they host. The anenome protects the clown and the clown protects the nem.

This is normal behavior for clowns. The shaking is a sign of submission from the one clown (normally the smaller) to the more dominant clown!

The twitching is showing that the clown is not the dominant one of the 2. It's like your twitching clown is bowing down to his "master"
