I am going to see how the week goes, they are currently in freshwater then will source my marine salt and refractometer/hydrometer next weekend and hope to start raising the salinity on the tank. The guy in the store mentioned to give them salt baths in a bucket each day, should I bother as the plan is to start bringing them to low brackish really very soon (like next weekend). The guide Dadof4 wrote on mixing salinity makes it clearer for me, may need little more guidance on actually doing it.
Will get some pics later when they have settled down.
Very quick preview
