Neptune's is the best place to buy fincky fish such as powder blue tangs and etc. They QT and copper everything for a 3 week min and 4 week min for powder blue tangs. And 5 of the 6 fish I have bought from neptune's are still alive, healthy and never had a problem. And I don't mind paying more for fish that has a 90% chance of living then a 60% chance of living. So getting to my point is there's not a unhealthy fish for sale in there.
