Beautiful tank you got there. However, you might want to steer away from caridina shrimp in this particular tank. The soft water that is required to raise these shrimps would eat away at that seiryu stone. It will raise both GH and KH. These particular shrimp need soft water that stays consistent. Most of us that keep these shrimp don't want any KH in the water. This is why we use remineralized RO/DI water and buffering substrate. Keeping a low KH will keep pH in the lower ranges when using buffering substrates. This is not a good idea, especially when injecting CO2 with shrimp in there. The constant pH swings from carbonic acid will be detrimental to them. They don't like any swing in parameters whether it be pH, GH or temperature. They prefer water temperature no higher than 74 degrees (68-72 being optimal for taiwan bees like RKK/BKK and BB). Water changes should be kept to a minimal as well (not good for EI dosing) and should it be dripped in to avoid sudden change.
I'm sorry if I discouraged you but you'll want to make some changes or even setup another tank if you plan to keep these shrimp, that is, if you care about the well being of them. Being as they generally start at $10 a shrimp, it could be a very expensive lesson to learn depending on how many you purchase. Take it from someone who has killed numerous taiwan bees in the past from "simple" oversights.
