Don't worry, acro, I won't name the store I purchased them from in a public forum.
Thanks for reminding us while we were on our "Jump to Conclusions Mat"
First off, let me say there is nothing wrong with this thread the way it is.
It is not that you can't name the store, but before anything like that happens, the ARC has a process in place that is listed in the Forum rules. I am only posting this as an FYI for anyone reading the thread, because stuff like this comes up regularly on the forum.
It is Forum rule 5:
"Sponsors are our guests here, and their stores should be treated as such. Infactual posts, libelous remarks, and even exaggerations of negative truths will not be tolerated. If you have an issue with a sponsor, the proper way to handle it is to talk to the sponsor / manager in person, then try via PM or email, then contact anyone in the sponsor store, and finally, if nothing can be done, the factual account may be presented on the forums."
The above process gives the Store the chance to make it right and protects the customer and the store from any unwarranted negative publicity. Fish die a LOT more often in the process of getting from the collectors to the LFS than anyone unfamiliar with the scene knows or probably wants to know. I know because I imported FW fish for a couple years from SE Asia.
My opinion as an ARC Member: I don't go back to LFS with dead fish because the best a LFS can do is QT and treat if they see issues. If a fish looks good enough for me to buy and is eating, then I assume part of the risk when I buy it. If a fish doesn't eat in front of me I don't buy it. The only way I would go back to a store would be if the fish died in the bag before I even had the chance to get him in the tank. Not to brag, but after being in the hobby for 36 years, my ability to judge if a fish is healthy is probably as good as anyone else's, so if I have any question about the fish's health, then I would buy the fish with the stipulation the LFS keep him for 1-2 weeks and if he dies in that time, then I get store credit. If the store is not willing to do that, then I don't buy it.
Some fish are more sensitive to shock than others as well. SW Cardinals may just not do well with changes in surroundings, or new water chemistry, or new tankmates. There are FW fish like this as well. They either die in the first couple days, or they live for a couple years.
One suggestion, and not to slight our Sponsors, but Live Aquaria sells SW Cardinals and they have a 14 day guarantee, so if this fish dies easily, this may be the way to go for this particular species if local purchase doesn't go well.
