I was just wondering if you keep all your inverts (corals, shrimp, crabs, clams ect) in seperate systems from your fish? Only asking because I have some snails right now and this will be the deciding factor if I quarantine them or place them directly in the display aquarium. I generally only quarantine inverts that are kept with fish or in systems with fish. I've placed several orders from live aquaria and have been very pleased but only recently have I caught on to quarantining (which I hate).
