All fish dieing

[Craigdillman]

lots of stores run copper in tanks to put ich at bay could be that some fish are sensitive to it

Sounds like its a acculmation issue tho , or heat related issue. If they accumulated them super fast then it could take up too 1 day and a bit to die from salinity stress

Could be ich or velvet in the water as well and they went into an envirmeont that was contaminated ?

or could be simple as stress of the fast move killed them

I kinda think you have a right to ask what happened ? I know its not there fault but if there a fish store they should be able to keep fish alive weather its from a shipment from hawaii or from your tank shouldn't make no difference>?

my 2 cents

at least try to get a discount off some new ones ?

Another possibility is Brooklynella. Even though it's known as Clownfish disease, it affects all. Some it kills and some are only carriers.
Brook kills just as fast as Velvet.

I bought some fish last year and the 4 of 10 that survived through a QT period of 3 weeks infected my DT fish. 1/2 my DT fish died within 3 days, including 2 of the 4 that were introduced.
I had to remove and treat the survivors with CP.
The carrier fish showed no signs so it was impossible to know it would happen.
It was my own fault as I panicked when the QT fish were dying and I thought they needed more room than my QT provided.

If you ever need to house fish again during a move, I'd suggest finding someone with a spare tank who can house them completely independent for you.

Would agree. Brook has a 90%+ kill rate and strikes out of nowhere. Very difficult to treat and would explain the complete wipeout in such a short time. You rarely see things like copper or low oxygen completely nuke fish without some amount of lead time and/or straggling survivors.

To add, my point is the LFS did not tell you how many fish they lost in the other five or six tanks, and how they died.
For all you know they lost numerous fish from a shipment, either before or during the time your fish were in there tanks
