Anemone epilepsy?

[RiffRaff]

So I'm repairing my tank from a crash and I'm slowly restocking. I have a 29g biocube and in this tank I had a matron clownfish. Real small like an inch and a half long. I had him about a week and then I bought another maroon that was about twice the size of the original. And also added a long tentacle anemone. The big one hosted immediately in it. That was one week ago. Today when I was adding another fish today and noticed the larger maroon was swimming all crazy. Doing backflips and barrel rolls and kick flips. This lasted about 30 seconds and he stopped sank to the bottom and my peppermint shrimp immediately came out an started to chow down. Nothing else was affected. All other fish are good. What could have happened?

Lta's are not a maroon clownfishes natural host.....maby the lta stung the maroon???? I wouldn't think that would be a normal response to get stung.....but that's a weird way to go out in any circumstance

twitching and eratic swimming is usually gill flukes
