Sith Vs. Wrasse round 1......FIGHT

[Darth Wader]

So I noticed that my Hammer coral looked like one of my fish had been nipping at the tips. So I kept an eye out to see who the culprit was. And last night, I saw my six line wrasse, nip at one of the tips, and then pretty much chomp it off.
I have never heard of six line doing this, if anybody out there has had this happen or has any ideas of what to do, I would greatly appreciate some advice. I think he underestimates the power of the dark side of the force because I tried the jedi mind trick on him but it didnt work.
