Just found these today on a wrasse I ordered from LA. Poor fish was covered in around 18 or so of these. FW dip got them all off. Not sure how I'm going to treat from this point forward. Luckily he is in a QT tank and was not introduced to the main display. However, there are other fish in QT with him, so they are at risk too. I'm thinking of doing a hypo salinity treatment for 1 week.
Here's a pic I took under my 20X microscope with the iPhone on the eye piece.
