3 fish dead in 2 weeks and it does not look good for the rest

Not to put a damper on things but it's only been about 4 weeks since Kien took the fish from you. Velvet can last in your tank for 6-8 weeks (after you remove all the fish) there might be a possibility that the velvet is still in your system and your fish might re-catch it. I really hope this doesn't happen but I would of waited at least 3 more weeks before bringing them home. I waited 8 weeks before I added my fish back to the display when I had velvet, and even then I was scared they might re-get it. Thankfully they didn't, but everywere you read says to leave your tank fish free for a minium of 6 weeks because the velvet virus can live in the system for that long, even without fish to host on.
