I do. I qt all fish, no matter what, I don't care where they came from. I've got two custom rimless tanks, roughly 30g each. On one tank I installed baffles to divide the tank into thirds (for smaller fishes), the other is divided in half (for larger fishes). I qt and observe, then deal with any problems that arise. For corals, I have a three stage dipping process. First dip is Bayer insecticide, then rinse with saltwater. Second dip is CoralRX, then rinse with saltwater. Third dip is lugols, rinse again. I then inspect all corals under a lighted magnifier for anything that might have escaped the dipping process. And if I see a nasty come off of a coral during dipping, that coral gets an extra stringent inspection under the magnifier, and put into qt if needed until I'm sure there are no bugs hanging about. One thing I have never quite figured out is how to qt snails and such, or nems.

As far as I am concerned, you cannot be too careful. One slip up and you have a whole lot of grief on your hands.


Anyone who has seen my table at the frag swaps has seen my sign. *Prevent STD's (saltwater transmitted diseases). Dip and quarantine all new purchases, and NEVER add water from someone elses tank to your system.* The sign gets a lot of giggles, but it also gets the point across.
