Half dozen of these 2mm guys apparently eating the algae on my front glass.
Body shaped like a ghost. Head is round and has a pouch shape that leads to a flatter body with notches tail. It moves pretty quick with a snake like zigzag.
Hoping they're only here to clean algae with my CUC.
Acoel Flatworm - sorry I missed it in the Hitchhiker Guide.
Six Line Wrasse is now on the shopping list because these flatworms are clearly eating my Copepods not the Algae.
