Thank you for the reply, but how can you say that DD doesn't QT their fish? Per the website, it says, in part, that:
"LiveAquaria.com's Diver's Den® Quarantine Procedure
Under our strict supervision and extensive quarantine procedures, we offer you quality aquatic life that is second to none.
All fish are quarantined and acclimated to captive conditions under strict protocols regardless of species."
Kevin Kohen - Director of Live Aquaria®
Proper Acclimation
Water is dripped over the fish for an extended period to slowly adjust them to the water chemistry of our fish quarantine system.
State-of-the-art Quarantine System
Once properly acclimated, new fish are then housed and maintained in our special quarantine system. To provide superior filtration and water quality, our quarantine system employs an independent filtration system with biological filtration, UV sterilization, ozone, and a large foam fractionator (protein skimmer).
Disease Prevention
Fish, such as clownfish, prone to common parasitic ailments like Brooklynella hostilis, are given repeated freshwater baths that contain anti-parasite medication. Other fish such as Angelfish, tangs, certain genus of wrasse, and several other specific species are given therapeutic saltwater baths. These baths contain praziquantel or other medications that eliminate flukes, protozoan, and parasites commonly found on wild fish.
To combat common bacterial infections such as Vibrio, therapeutic baths containing antibiotics such as kanamycin, nitrofurazone, Neomycin and other commercial antibiotics are given. Open wounds on fish are treated and healed with a special topical treatment. In addition to the baths, all quarantined fish are treated with copper sulfate and a 37% formaldehyde solution to combat Amyloodinium ocellatum and Cryptocaryon irritans.
Quarantine and Observation Period
The quarantine period for each fish ranges from a minimum of two weeks to several months for more delicate species."
There is more information there, but I just copied/pasted what I thought was relevant. Any other thoughts?
