Hello all, I am new to shrimp keeping and need some advice please. 4 weeks back I moved my CRS, CBS and white shrimp to a new tank and everything was going fine, but for the past 2 weeks my shrimp seem not to be moving around very much and just seem to hide. They where quite active in the old tank and i do not know why this is happening, have not had any deaths and a few of the females are berried. Any advice would be greatly apreciated. Cheers
