i just got some ghost shrimp from the lps, where they were in brackish water, but the lady there said they were freshwater(huh?) how do i tell if they are really supposed to be in brackish or fresh? i wanted to breed them to make food for the loaches, the pet store said they would just have babies if i left them alone, but that they might eat them so i should take out the adults...wish they had a better idea of what they were talking about...anyone here got more info?
