OMG... Not another one!
Yes folks I lost number cardinal tetra number 9 this afternoon. I just don't understand why and may never. The water params are spot on where they should be. The tank is planted and there is still plenty of tannins from the wood in there to make these guys feel right at home.
Ammonia - 0
Nitrite - 0
nitrate - 5ppm
temp - 77F
pH - 8 high but stable
The fish are all eating and swimming normally meaning no erratic behavior. Their appearance looks good, nothing unusual to their physical appearance. I just wonder if I got a bad batch of fish?? I had to special order these from Pet Supplies Plus and I picked them up the day they came in. (yes probably not the best idea) It is simply disappointing to see this happen and not know why. The only thing that I can think of is stress... but after a week?

Nah, I don't buy it. One or two or maybe three but 9. no way! Your water values don't show anything as you know.
I had a bout of this in december, something the hatchets brought in. A perfectly healthy boraras would suddenly keel over and die.
Just to be sure, have you ruled out agression?

Not sure about your supplier, but I know that many cardinals are wild caught, and therefore require parameters that more closely reflect their natural habitat. While most fish are very adaptable to a higher pH regardless of their natural origin, I know that cardinals can be different in this respect. They generally prefer a lower pH. Just my two cents.

Sorry to hear that.
But i'm leaning towards the others, and especially rauulfd4.
Ask your LFS about their supplier and if they are wild and try to gather as much info as possible.
Maybe it is too much of a pH swing, or hardness swing-something funky like that.

+ 1 to Raulfd4 on his pH comment. They also like their water soft and well established tanks. I always add them last to any tank I've set up.Perfection is not attainable, but if we chase perfection we can catch excellence.

Thanks guys... I will see if I can get some additional info on the supplier. I know for sure it is not aggression, these are the only fish in the tank.

I did find out that they are captive bred in Florida. The only thing now that I can conclude is it is a pH issue which really sucks. What can I do to maintain a stable lower pH? Tetra makes a black water extract... anyone ever used it?

Talk to me about how you got the fish. Did you bring them home and drip aclimate or were they unbag and dump or just dump a cup every 15min to aclimate? Did you test temp difference? Have you seen chasing? Are they losing color prior to dying?
If they were wild, it could easily be a combo of stress from collection to destination. I am willing to bet these fish came from a +7 ph if its in Florida. We are on limestone reserves and even the discus I have live in that same liquid rock.
In a 55gal I had, Red Minors were the source of killing my entire tank one by one with no injury visable. This included 20 Cardinals. I would bet aggression + stress of shipping could have done it. Also did you Qt the fish? Something could be different between Ohio and FLorida disease wise.
