Creating a Woodland Stream Ecosphere (With PARASITE!)

This is a video of me creating a woodland stream ecosphere. I really look forward to seeing how this ecosystem progresses. For substrate I used gravel from the stream, which contains organisms. I also used larger stones and sticks from the stream. I was quite surprised to find an ecto-parasite growing on the chitin of the amphipods after building this ecosphere. I have collected amphipods from this stream several times over the years, but have never encountered anything like this before.
