Dactylogyrus rubellus is a platyhelminth parasite which lives on the gills of freshwater fish in the family Cyprinidae. These beautiful little worms have direct life cycles; mating on the fish gills, they release eggs into the water. The eggs hatch in the water, releasing larval worms which then swim up and find and attach to a new host. Dactylogyrus do not switch hosts once they attach.
