Hard to say. How old is the tank? Did he introduce them all at the same time (fish)

Where the fish healthy? What kind was it?

he say the fish just stay in floor and die, he go to store, and 3 hours back all die, i ask him more detayls.

Did he have a cucumber in the tank? When cucumbers die they give off toxins that kill fish but not other invertebrates.

I would recommend doing a large water change and running a cannister with lots of carbon before trying to restock this tank.

It could be a variety of things, and there's not enough information to give a solid guess. Though the specific gravity is quite low, it's nothing that will kill the animals as long as they were acclimated to it. I suspect disease. Did he ever quarinitine?

another question. did he acclimate them right? what kinds of fish were they? did he QT? what are the inverts? how many fish did he add? how big is the tank?

I'm leaning towards "they are not healthy to begin with".

Cyanide-caught is possible... Ich infested is possible... velvet? Also possible. Does he quarantine new purchases?

Maybe they are sick but nonetheless he should try and add only one at a time. This will create less chance of loosing them. Also he should check with his LFS to see what they are keeping the fish at.
