(Nov.10th 2008) The so called „gold dust disease“ of the bloodfins is a very interesting phenomenon, which happens to very many
bloodfin species. The best known one surely is the gold-tetra, Hemigrammus rodwayi whose number of gold-dust-sick
animals in nature is higher than of the normal coloured ones. The gold-dust-sick animals were even considered as
own species (Hemigrammus armstrongi). The cause of the gold dust disease is unknown. Often it was theorized that
the disease was a result of a parasitic flatworm infection passed during the young fish stage, but this was never
really proved. It is a fact that animals covered by the gold dust disease are not restricted in their health or
life expectancy. Also it was never successful to transfer this phenomenon on descendants bred inside the aquarium.
Therefore all gold tetras are always and only wild caught fish. A display aquarium with different gold tetras, such
as ornament tetras (Nannostomus beckfordi), cardinals (Paracheirodon axelrodi) and gold tetras (Hemigrammus rodwayi) looks fantastic. A highlight in such a tank are the rare and particular attractive redback bleeding heart tetra (Hyphessobrycon pyrrhonotus), which Aquarium Glaser is offering currently.(Photo & Text F.Schäfer)
