Marine velvet(Amyloodinium ocellatum) in microscope
 
01:32
This appears to be marine velvet(Amyloodinium ocellatum) at 800x The first half of the video shows a group of dinospores(free swimming stage) and the second half shows what appears to be an early tomont or mature trophont that fell off the fish. This is in a water droplet that was collected after a 5 minute freshwater dip of an infected passer angelfish. The large trophont falls off the fish due to osmotic pressure, then can be seen with the eye in the dip water, frequently referred to as looking like 'snow'. The sample droplet was collected to attempt to capture and observe several of the released trophonts. As a warning to fellow fish-keepers, this video was take more than 6 hours after the slide was prepared, so the live dinospores are able to live in pure freshwater for a significant time.
