It is hit and miss with aquatic collection. I've had fish do just fine, and lost others--usually they disappear in my tank never to be seen again. I once had velvet and it prob. came from t hem, but the fault was mine for adding way too many fish to a small tank at one time. It was the stress that brought it out I'm sure. Never had velvet or ich from them again. Just fish that don't always make it and that is probably more to the way fish are shipped, stressed and sold--an industry thing. Same with corals. Some make it, some are already stressed even if we don't see it at the lfs. I still shop there. My choices are few. Randy's in stockton surprised me. Got 2 dragonettes that are thriving and a watchman goby doing well. Another goby disappeared in my tank. Could still be there somewhere...
