Matted Filefish or Copperband Butterfly?

[ponokareefer]

So after nothing was happening with my filefish, my brother let me borrow his copperband. 2 weeks later, the aiptasia is gone. I didn't see either fish eat it, so can't confirm for sure it was the CBB.

I added 3 peppermints to my 225 not expecting much and have yet to see them since introducing them but the aiptaisa are disappearing so I guess they are working.
I love cbb's but don't trust them with clams.
