QT a CUC?/ how do you bring in new livestock

[kyl]

Forgive the older thread bump, but this is a curious topic to me given I've set up a new 65 gallon tank and have the ability to properly QT fish now (and have started on the first two additions already). For inverts it seems like a lot of work and delay for CUC, though at the (slight?) risk of crypto tagging along and making the fish QT somewhat pointless.

I know we have a lot of GVRD people on this board, and it seems the local retail livestock quality lately is not so great in some of the chatting I've done over the past weeks. I'm still on the fence towards not 72 daying the inverts, but if they're in tanks with suspect fish then.. well you can see where it's going.

Just being paranoid, rash, or responsible thinking? I haven't seen any signs of crypto in my nano tank so far, but you never really can know until the visible signs hit.
