Anthia temperment

[sds]

Hey guys..I have a pair of Bartlett Anthia's that I purchased from my LFS. They have been living in harmony (famous last words, huh?) until recently. The larger one is showing aggressive behavior towards the somewhat smaller one. There hasn't been any nipping (not that I can tell anyways). Would re-arranging the display help settle the big one down? I've had them approx. 1 month in the display tank and the bad behavior started about a week ago.
Thanks for everyone's help!
:notsure:

yes it will help. Take out the aggressive one and rearrange the rocks. Add him back in a about a day and he should be fine.
