More infections!

So my next experiment is off to a good start! I've infected 19 fish and have only 101 more to go!  And I'm behind on every other aspect of my project!  Arghh!  Too much to do, not enough time!  Luckily I HAVE to leave the lab by 6 tonight because I'm babysitting for one of the lecturers...great kids and they spoil me with a fabulous dinner!  But my life is now revolving around my snails producing my parasites and me getting them into fish as fast as possible!
