What the? About to quit.

Cyanide was my first thought, but then I thought that it would be really weird for them to all die on the same night. Wouldn't it?

Yes.
Were they all caught at the same time? I know you brought them home separately, but what about when they got to the store?

I'm suspicious of the piece of tilipaia left in the tank overnight. Maybe it had somekind of preservative on it or something. I really doubt it was cyanide, even if the chromis were all from the same batch, they wouldn't all die at the same time. Not all unexplained fish deaths are due to cyanide.

 

[ReeferMO85]

They most likely came from the same batch. As far as the tilapia, people put seafood meant to be eaten by people in there tanks all the time, right? Shrimp, fish, scallops, squid, I've even heard of people putting in garlic, corn, and broccoli.

I might suspect the tilapia, IF other animals were affected too - but they were not. That is the quandry - ALL his other animals are ok, which means it was the fish themselves, not his tank. Odd they all turned belly up the same night, but not so odd if they were all caught the same day, handled the same, etc.
No, not every unexplained fish death is cyanided related, but when the tank mates are fine and even the chromis seemed fine up until death, that sort of clinches it for me...

SOmewhere online, there used to be a site that kept tabs on the marine fish industry, and a list of who you could trust and who would buy from illegal catching places - don't know where it is or even if it still exists, but would be worth googling if you really want to know.

I thought cyanide too. Cannot be ruled out. The death of my second Coral beauty is suspicous of this horrid practice. The fish ate 2 hours after being introduced into my tank. 8 days later turned pale & disintegrated before my eyes. Horrible! Water chemistry was fine ( unlike now, my phospates are too high, water change long overdue!) & double checked.

They need to increase the fine and penality for using that method. I guess the sea is just to big to watch everyone

I read somewhere that its not as bad as it used to be. Only one isolated area. I wish I could find that article.

Before doing that it would be nice to get a method to detect it that doesn't involve sacrificing the fish to be tested.

It's not as common as it once was, but it's still too common (as is dyeing corals).

My first guess would be the oxygen content overnight . It has been shown in many tanks to drop signifacantly at night . If it is low , fish have been observed rising to the higher parts of the tank at night to try and obtain more oxygen , I would check for that . I also agree with pactrop they are little huffers and puffers just like tangs which are also know to suffer in low oxygen content .

I agree with this statment. I observes this when I had my chromis a long time ago. I would see them floating underneath my hang on filter at night, while at morning they looked fine. I dont remember how but they eventually all died. That was a long time ago though. IMO they just arent shipped good or taken care of well at the lfs or watever b/c everyone thinks they are so hardy that you can bypass normal procedures. my .02$.
