hi, i went to my LSF and they told me not to add my CUC untill i have my fish and corals in and they also said to wait at leats untill my tank is 5 months old can anyone help. and also i asked them about different snails which the names i have heard on here planty of times and they didn't know what they were i'm in australia so do you think that could be why they didnt know them thaks sorry its so long
