I recently had a sick fish brought to me from a pond where the fish were dying in droves.
For those that are interested, I have a live video of chilodonella that I have added to my collection of parasites that attack fish.
I know this link works with windows media player but I am not sure it if will work with other media players.
Live video Chilodonella
There are also "still" pictures using a microscope on the same page. Oh yah and a photo of gill damage the chilodonella caused.
