Please post some more feedback on these questions when ya'll get a chance.

-Does Purchase size matter for a higher survival rate? Is it true the LARGER the fish the better?
-Should I go Sand-less and Rock-less, in other words completely bare in the QT?
-Should I use a UV sterilizer since I'm sure 2 have died from ich.
-Should I medicate them in the QT or pre-dip the fish?
-Should I use my Spare 45 Gallon tank or just convert my Spare Nano Cube 24 into the QT tank?
-How long should I leave him\her in the QT tank?
-Order Locally\In SA or use Mail Order?
-Should I get rid of my Dej. Sail fin Tang(6in) and Purple Tang(4.5") as they think that they own my tank since they have been in there for over a year.

Thanks In Advance.
