1. What does the term C-numbers mean

 

 

 

 

 

 

 

 

A.

 

 

 

 

 

 

 

 

In 1993 Hans-Georg Evers a German aquarist and a leading light in the aquarist world implemented this code for the German magazine DATZ due to the many undescribed species that were entering the hobby without any name.

 

These number codes (C for Corydoras) meant that the whole aquarist world would know what each specimen was as it will be many years before these code number species will be described to science. When any C-number is described the corresponding number will be retired.

     

2. What does the term CW-numbers mean

 

 

 

 

 

 

 

 

A.

 

 

 

 

 

 

 

 

DATZ stopped this coding system with C159 but there were still unidentified species still arriving in the hobby so in 2006 Ian Fuller who runs the corydoradinae website, www.corydorasworld.com decided to carry on with this same coding method with his CW (Corydorasworld) numbers. The latest number as of February 2019 is CW154.

The CW number system is mainly internet based and is published through his site.
When any CW-number is described the corresponding number will be retired.
     

3. What does the term L-numbers mean

 

 

 

 

 

 

 

 

A.


 

 

 

 

 

 

 

Again the german DATZ magazine was at the forefront of introducing the L-number code due to the many undescribed species that were entering the hobby without any name. It was the December edition of 1988 that Rainer Stawikowski first introduced the L-numbers, L of course standing for Loricariidae.

 

As of February 2019 the number stands at an incredible 513.
When any L-number is described the corresponding number will be retired.

     

4. What does the term LDA-numbers mean

 

 

 

 

 

 

 

 

A.

 

 

 

 

 

 

 

This code number system was put in place by the the German aquarium magazine, Das Aquarium, the LDA standing for Loricariidae Das Aquarium. This system was supposed to run alongside the L-number classifications but this magazine closed in 2005 and the last LDA number was LDA102.

When any LDA-number is described the corresponding number will be retired.
