I can explain how to do the acclimation process. You would naturally want to keep them in full freshwater then just slowly raise the salinity of the tank once it reaches a salinity of 1.020 specific gravity, then just drip acclimate them to raise up the last few points. Remember these fish are pretty small and you should be careful with what you put them with, naturally you would want to keep them with peaceful to semi aggressive fish. They will be pretty shy at first but if you do have 4 or more they will become to school. This is great because there aren’t many peaceful schooling fish out there and definitely not ones with beautiful patterns and colors.
