What diseases can yabbies get?
Porcelain disease (also ‘white tail’ or ‘white muscle’ disease) can occur in the yabby; it is caused by a microscopic, single-celled animal, the microsporidian Thelohania. The disease is easily detected in the late stages, when the underside of the tail turns white and the walking legs often become splayed and rigid.
Can yabbies get worms?
Surface temnocephalid worms The marketability of yabbies will be reduced if the shell is stained or is covered by surface parasites. Their unsightly eggs laid under the tail and around the gills in particular are resistant to these baths and the eggshells remain attached even after the worms have hatched.
How is Epistylis treated?

How do you prevent Epistylis?
The best way to prevent Epistylis infestations is to stock with animals free of the parasite. However, if it is already present, improving water quality and container sanitation, decreasing bacterial and nutrient density, decreasing animal density and improving nutrition will help to control the problem.
What causes whirling disease in fish?
Whirling disease is a parasitic infection of fish caused by a microscopic protozoan that destroys the cartilage of juvenile trout, resulting in skeletal deformities and sometimes whirling behavior. Seriously infected fish have a reduced ability to feed or escape from predators and mortality is high.
