What fish?

[paragrouper]

What fish will eat red planaria flatworms?
Bonus question: are there any flatworm eating fish suitable for a 32 gallon tank?

I noticed one on my front glass. Then, after looking, I found a number of them perched atop my stylocoeniella. I siphoned up those I could find and I know I can use flatworm exit, I just want to know if there are any alternatives to chemicals.
