Flat worm

[fishface]

why do anything at all?? as the article you linked to says:

Amphiscolops sp., a harmless acoel that "shows up" at times in reef tanks. i noticed a while back i had them as well so out i went to get "flatworm exit". then instead of dosing, i decided to watch and see what happens instead...nothing really, still see a few around every now and then but it's not really an issue IMO. they don't really seem that evil...
