I have recently ordered silver tip and ember tetras. The way I understand it fish are purged before shipping and of course don't eat during transit. It is suggested to not feed your fish the first 4 to 5 days when giving the QT trio. My question is should I take a few days to feed them before starting the QT trio? Would they be ok with 4 to 5 more days of fasting if I instantly started the quarantine meds?
