Or any thing wet,that was in said LFS tank water...Why not just QT.Ick is just one of many nasties we can introduce to our tanks.QTing is a good thing.I dare anyone to say its not and support that statement.I leave my QT up and running 365,its full of LR and hermits.Sometimes i just sit and watch it,the hermits are always fighting and trading shells. Take short cuts and possibly pay the price,or QT and look into your DT knowing all is safe.Yes,i know there are people who don't do it and have never had a problem.Not everyone is that lucky,and to me thats just what it is ....luck.
