Parasites...yuck!

[Myka]

So I was inspecting my Jawfish which arrived DOA. I notice that there are "rice grain" things under his skin near his tail, so I give him a little slice and pull them out. They are ALIVE!!! Little worms shaped like sperms (rice grains with really long tails, like 1"). Any idea what they are?

And on that note...I bath all my new arrival fish in PraziPro as stated on the back of the bottle for 15 minutes. Thing is, those dosages are for treating a QT or tank, and are designed to have the fish in it for much longer. Do you guys know how strong you can make that solution to use for a 15 minute bath and have it more effective?
