The chart is very misleading in that, it does not mention the scientific names. Cambodian Dat, Siamese Dat, Indo Dat, Silver Dat, those are common names in exception of the Silver dat, which could be the Quadrifasciatus. But the rest are mostly used by fish stores that doesn't really know what they are selling.
Datniodes are fascinating to me because they live a long time, they are rare in the hobby especially the large ones...12 inches and over. Their personality is so intriguing because of just the way they stay in front of the tank when you "their keeper", come close to it, they do not run and hide like some fish. It's like they can see in 3 dimension, but I am not really sure if they can...In addition, they have never been bred in captivity, and not much is known about them, breeding habits, places they are collected, and NOT one hobbyist has been able to differentiate the sexes.
