Kyphosis
Anterior-posterior curvature of the spine
Parasitic nematode of the intestine. Found in marine fish. Can infect all species, but typically is found in butterfly and tangs, because of their eating habits. Parasite needs intermediate host, e.g. Shrimp. There are several species of this nematode parasite, many found in S.American rivers, but the symptoms they cause are very similar to the one we feature.
Can be treated, and it is seldom quickly fatal. The outlook with careful treatment is good.
