picked up some FWE tonight as a last resort. going hunting for a small 6 line on the weekend

Are you sure a six line is really what you want ? :lol:

Maybe something less psychotic, like a canary wrasse?

I totally agree with this statement..

go for any other wrasse other then those six lines. the yellow are cool i used to have 3 of them and that chumed together through the tank.

If it has the scalloped tail, it's not the same as an AEFW which look like this:

I had clear flatworms similar to the first photo a while back in my 9 gallon.
A dose of PraziPro took care of them fast without any visible harm to the corals.

If your tank would sustain a Yellow Coris Wrasse (tankmates? size of tank?) then they are great option for flatworms. They are not aggressive like many other worm-hating Wrasses. Both of my reefs have Yellow Coris Wrasses in them. They are good janitors. :)
