Does this look like a flatworm?

That isn't enough. Dips will not do anything to any eggs that might be on it. Your only options are to toss the frag or QT for at least a month. Doing weekly dips to remove any new worms that have hatched out.Johnos said:He's already been informed.
(I received the frag.)
Which, I'm ok with, since I have already taken the precautions I feel I needed to.
(New frag plugs, FW dip, then another FW dip.) It may kill the frags to do so many dips after being refragged.
