Clown fish aggression

[Deus ex machina]

I have a number of different fish in the tank (13). Before she started harassing the Tang, which I introduced two days before the first spawn, she must have been harassing my Citron Goby because it became wraith-thin. I never actually saw her attack another fish until she started attacking the Tang. On the other hand, she started attacking the turkey baster at feeding time a few weeks before the first spawn.

Yesterday I set up a turkey baster bobbing near her spawning sight and she was distracted enough to make only the occasional sorte at the Tang.

I think I'll try the mirror trick.

Thanks for your help.
