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.
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.
