If you have information on the bamboo, please share it. I haven't encountered any successful reports of breeding these shrimp. So, it's difficult to say for sure that they do in fact need a different salinity, compared to the amano. I'm sure it depends on a bunch of factors, including such things as the shrimp's geographic proximity to the ocean where they were caught. There is more known about the amano raising, and since it should be a similar process between the two species, relatively speaking, I'm using the amano process as a baseline for the bamboo.
I can't say how things are going for that species, as the larvae are mixed. It's not until they develop into shrimp that I could even begin to tell them apart. My female bamboo and amanos have roughly the same cycle for carrying eggs, so I have simply been collecting all of the larvae, thus the mixed batches.
