Abstract
In some stocks of fry of 3 aquarium fish species, Schulz's corydoras Corydoras schultzei, tiger barb Barbus tetrazona and black telescope eye goldfish Carassius auratus, 20 to 90 % mortality occurred. The mortality was caused by a ciliate protozoan which did not resemble any of the known fish ectoparasites. The deaths occurred in fry kept in densely populated aquaria. The protozoans were attached to the epithelium with their cytostoma and often covered the body surface in large masses. The protozoan was identified as a Coleps sp., previously known only as a coprophagous species or a predator of protozoans. This is the first report of losses caused by a Coleps sp. in fish fry.
