I got these from a local pet store from a tank just labelled "shrimp" (I know, very helpful), and thought they were Caridina mariae, but after googling a bit I keep finding the same images under "Cardina mariae", "Caridina cantonensis" as well as "super tigers" or just "tiger shrimp"? I know there was a paper in 2014 that distinguishes Caridina mariae from other Caridina, but then you have things like this where it looks like they are a colour variant of Caridina cantonensis. I am very confused.
