Anthias going crazy?

So I just got an anthias from the lfs yesterday and everything was fine swimming everywhere and even eating. Today I noticed she is in the same spot at the back of the tank trying to fight her reflection. She has been doing this for about 5 hours and seams to be exosted because she is lying down in the sand at the spot she has been "fighting."

So should I be concerned? And is there anything I can do?

 

any help or info?

 

Sorry but bumb

 

Try shutting the light off or scaring her out of the corner with something and see if she goes back - if so you have one nutty fish! One of my scooter blennies (male) fights with himself in the reflection every once in a while but it eventually does give up. Sorry I couldnt be more help

 

i think its cos you have a single anthias. Is it definately female?

 

I don't know if it is the same, but my sixline did this for about a week. He just swam up and down and all around on one side of the aquarium and would peck at the glass. He didn't get exhausted, or at lease from what I could see didn't, like your anthias did. After about a week he stopped
