Hi Zoidburg, thanks for all the info. I didn't know about Caradina orange shrimp. Both my types of orange are neocaridina. I have had the regular davidii in orange for a while now, that's the darkest girl in the pics I posted. About a year ago I bought a small colony of Sunkist orange that had a number of rili in there too, but their hue of orange is totally different to my other orange davidii, more of a burnt yellow. So I was wondering if genetically they are the same colour being as it's so much deeper on my original ones than the newer Sunkist. The babies from the cross appear to be mostly the same colour as the Sunkist but none with rili patterning. There were two that were darker true orange but not as dark as the mum.
