This is exactly why I refuse to buy fish kept in low salinity. Store owners say it prevents disease. IME it suppresses disease then when you get the fish into normal salinity the disease rears its ugly head. I had the exact same thing happen a few years ago. Bought a fish in low salinity and after a few days velvet started killing fish in my tank. I managed to save a few but lost many. I no longer purchase fish unless they are in a tank with coral or inverts or both.
In the original post, the deaths of the original fish happened within 12 hours (with the exception of the tomini which was 36 hours. so its still super rapid which is why I was at a loss. it WAS pointing to velvet being that one of the fastest disease but although I didn't have pics, I did look at the fish and didn't see any spots. i know now velvet can occur without certain symptoms i.e. sugar spots.
Thanks for your contribution to finding the issue. your comments are noted.
all the LFS keep their fish separate from the coral with exceptions of maybe wrasses, inverts, dragonettes. theres one store that has fish with their coral as well as separate but they charge extra to get them b.c the time it takes to get them from their display tanks and hitting the coral.
That's too bad. I have 4 lfs and one has seperate tanks with fish only and they do run copper but I have not confirmed at therapeutic levels but the salinity is 1.025 so I will by from them. One other all tanks have fish and coral with inverts so I buy there.

Well geez, everything in my tank is dying really fast let's wait a few days and throw 3 fish in there and see what happens....really considerate hobbyist with a high moral standards for the well being of his animals.Thanks for your contribution to finding the issue. your comments are noted.
but seriously did you read every post in this thread?
been keeping fish coral and inverts in this tank for 6 months so half of your rant was just ruled out already. I had talked about icp test but wasn't sure if a toxin was the issue. 50$ is more than some free chromis.
The only thing I didn't think of (or anyone on here talked about) was the voltage which is what someone mentioned today at the LFS after the chromis went within 6 hours. I will be testing this theory when I have my voltage meter from work tomorrow.
To be fair, I came on here to find out and am well prepared to do a fallow period. I typically do formalin dips with my fish but ran out and didn't realize it at the time. Voltage stray wasn't a thought considering all equipment is new and was going through process of elimination. most likely to least likely
If it is voltage stray then I would've waited 2 months for nothing and solved nothing. Someone had to help clean up Chernobyl.
this is all good info. i will be cautious in the future with this info. probably setup a qt. being relatively new with marine fish outside the nano world of clowns and gobies, ive been going for the cheaper and hardy fish. anything over $100 is a no go right now. if i did venture to the $300 fish, for sure i would be doing the qt route.That's too bad. I have 4 lfs and one has seperate tanks with fish only and they do run copper but I have not confirmed at therapeutic levels but the salinity is 1.025 so I will by from them. One other all tanks have fish and coral with inverts so I buy there.
Maybe ask your lfs owner why they keep low salinity in the fish only tanks. If they say it is to prevent disease then they are misinformed or lying IMO
This is a quote from @Jay Hemdal on the subject whom I trust more than lfs owner.

Do you actually QT or treat without symptoms?
Jay I know people feel the blackworms offered for sale in the hobby are the same as tubifex but Blackworms are much fatter and a different color and have different "mannerisms" and grow in different places. Tubifex are typically found in drainage ditches and horse feeding troughs while...
did you mention the voltage today or before?
Stray voltage is a red herring and doesn't harm fish anyway. Also confirmed by Jay H (love having him on staff here) and myself. I had 50 volts in a tank and didn't know it untill I stuck my hand in the tank while standing on a chair. Yep I jerked and fell off lol. Fish and coral were all perfectly fine becuase they aren't grounded.
Many people believe it does. It's one of those things that's been repeated so many times it becomes internet fact. It also helps people to explain unexplained deaths.
so your vote is fish death by velvet in 5 hours? just curious. ill still check voltage/amps in the tank tomorrow
ICP will only catch elements that are out of balance (like heavy metals or salts). It won’t give any information on organic toxins.
Did I miss it - what was the salinity of the store’s tank that had the green chromis on it compared to yours? Death in hours is either the fish were already sick when you got them, or it was an acclimation /stress issue.
gotcha. yeah ive read it and symptoms seemed to match.
this is why i didnt jump straight to getting icp test when disease is still an option.
yeah i mentioned it on previous page. no worries.
Most toxins affect invertebrates, especially corals, before fish. These are best removed by first identifying and eliminating the source, and then big water changes (both carbon and ozone are limited in what they neutralize, but water changes work for all toxins.
I'm not super knowledgeable on the chemistry side of things yet, but carbon does help with some toxins, IIRC ozone does as well, but - to answer this part - there are definitely toxins that impact fish more than inverts; they're called ichthyotoxins.
It checks for pollutants also
