hi i have some cherry red shrimp.i have raised some from them. so i gave my sister some of the small ones, and i also gave my neice some ...well my sisters have turned to be clear. her PH is 7.8 and the temp is 74. the ones my neice have are red like mine..i think my sister has something to do with the water hardness because her water is very very soft...does anyone know any thing about this...please help.she even has one that has a saddle but it is clear too..And they came from mine so i know they are rcs.thanks
