People interested in high grade CR are sometimes keen to collect so called ‘red line’ shrimps. This expression refers to the fact, that some high grade CR have SSS patterns through selective breeding of low grades. Besides, it’s assumed to prove that no Snow White shrimp has been crossed in to improve patterns and grades.

In addition to the red line concept, some breeders’ names are a guarantee for high quality: Suzuki, Shirakura, Ueno, Hakata and Ebi-Ten are well known Japanese breeders who have been working for long time on shrimps. Also ASSA, a Japanese breeder association, stands for CR with deep color density. In Germany, some CR are sold under the label ‘Japannachzuchten’ (=offspring of Japanese lines) or new line names like ‘Ebi-Ishi’ – but what’s all this really worth it?

The truth is most German folks buy high grade shrimp from Asia, spawn them and sell them. Often, you even do not know if you get rejected second choice shrimps – or even some which have been crossed with unknown stock. See: the label ‘Japannachzuchten’ is nothing more than a marketing tool since you cannot prove the genetical background but only trust your reseller.

It is not quite clear where Snow White shrimp come from and different theories are discussed in the net. As far as we know by now, there are two different strains:

A pure white Snow White which shows very light and brilliant white color. It comes from selected Chrystal Black (Black Bee) or Crystal Red shrimp (Red Bee). Some tend to have a bluish touch. This shrimps are probably the ancestors of the Taiwan Bee called ‘Blue Bolt Shrimp.

The Golden Snow or Skeleton Snow has a warm golden or even pinkish shade. It’s origin is mysterious too. Some say it comes from Crystal Red (Red Bee) shrimp and recessive to red. Others say it is a special kind of its own.

The reason why the genetically background is discussed controversially is that not every Snow White or Golden Snow seems to have identical genetic information. The results one can get by mating:

• Golden Snow X Golden Snow = Golden Snow
• Snow White X Snow White = Snow White, Grade SSS, Grade SS
