These guys are about 2 to 3 mm in length. They feel like a garden
slug when pressed against the side of the tank. They consume the
extra Brine shrimp and collect against the areas of the tank wall
where the shrimp collect when not eaten.
It's a little hard to tell from the picture, but they look like some type
of planaria species or similar platyhelmenthes Flat worms). These are
scavengers and they will eat eggs. They normally don't come out until
evening or night. I would suspect that any fluke medicine will also kill
them since flukes are also flat worms.
