Female Bluethroat Trigger

[broknheadlite18]

I have a female bluethroat trigger that is about 2 1/2 inches long in my 75 gallon tank. She is a fairly docile fish, especially for being a trigger. Tonight I added a couple new fish, she chased them for a few minutes, but eventually settled into the new tankmates. Now, about 4 hours after the tankmates arrived, she is acting a little strange. She is swimming normally, guarding her normal area, eating and excited to see me whenever I come to the tank, but occasionally she has been doing what appears to be a barrel roll. She'll be swimming along and slowly rotate in an entire circle. There are no signs of ich or any external parasites in the tank and her resperation is normal. Any ideas? Thanks!

I am not exactly sure, but FWIW I have owned a few different kinds of triggers and the blue-throat was definately the most "playful". So if it isn't running into things I wouldn't worry. I have also watched a clown trigger that liked to swim up to the output of a powerhead and do multiple backflips across the length of a 4 foot tank.
