Best acro flatworm eater

[Aquattro]

I'd go with the six line. Coris wrasses get large and eat things you probably don't want them to.

A reminder to people...always assume the frag you just got has pests and treat accordingly. Brennan found out about these worms because he gave me a frag that I found a flatworm on. FW dips are the only preventative measure that I know of. 30 seconds in temp corrected RO water and constant basting to dislodge worms works wonders and the frag is doing awesome 24 hours later.
Thanks for the frag Brennan!! I still have to pay you for it too!
