Symptoms

Raised bumps
Solid looking raised bumps are evident on the skin.
Abdomen sunken
The lower part of the fish's body is hollow and wasted.
Growth poor
Parasite infested fish show very slow or no growth, as parasite is taking the food.
Hiding abnormally
Fish hides behind rocks or suchlike, appearing seldom if ever.
Muscular atrophy

Causes

Cercariae which develop as a 2nd stage of digenetic trematodes. Transmitted by an intermediate host, usually snails. This is also the cause of 'Black Spot' disease.

Prognosis

Fatal is left untreated. Quarantining procedures can help to reduce infection. Keep tank or pond clear of all snails, so the life-cycle will be stopped.
