Water Parameter Question

Just had a thought, while trying to plan out a new tank and thought I would ask. Since fish require such different water parameters, how does the LFS keep such a wide variety of stock? I realize they can adjust temp. fairly easy but what about pH and dGH? My LFS carries everything from Discus and Cardinals to Livebearers and African Cichlids. Given that fish have such different requirements, are the ideal water parameters just a guideline? Can most fish be acclimated to different water chemistry? As an example, (I am at the store about once a week just to look around) there is a tank that has had German Blue Rams and Platy for at least 3 months now. Both species seem healthy and active.

Had another thought, sorry. Assuming the pH and dGH of the LFS comes from the same water supply as my house (I live within 5 miles of the store), wouldn't all the fish in the store have already been acclimated to the same water parameters as my own.

Sorry, I just can't stop thinking about this. Since most of the fish we keep have most likely been tank bred for many generations, why is it so important to keep them in water parameters that mimic there natural environment? Or is it, haven't they most likely adapted to different water parameters. I am starting to think that keeping them in stable water conditions may be much more important. Please, correct me ifI am wrong.

Most of the time, the fish in the tanks at the pet store haven't been there long, and won't be there long, so the store employees don't put too much effort into making sure the water is right.

Secondly, I have found that most of the pet stores don't seem to care much either. You will often see fish that should never be kept together in the same tanks, and things of that nature.

The store I am speaking of is family owned and run for over 30 years now if that means anything. It is not just the fish for sale, but they have multiple display tanks with multiple different species. For example, they have a 600 gallon African Cichlid tank which I believe would require hard alkaline water and a Discus/Rummy Nose tank which would be just the opposite.

You are right that keeping fish in stable conditions is much more important than ideal water parameters so long as those parameter's are not too different than what fishes are able to thrive in,or suggested range.
Is a big difference in my view, between waters that fish may survive in, and waters that they will thrive in.
Fishes kept outside suggested water parameter's for that particular species,often do not have developmental capabilities that they would in ideal water chemisrty(or close to it) ,and appear stunted, or have shortened life spans ,along with possible increased suceptibility to bacterial or parasitic pathogens.
Tank bred fish can and do adapt to slightly different water than what theyr'e wild caught cousins or ancestors are found in but not all fishes adapt well or thrive.The difference in my expierience, is fish that live years, and fish that live but a few days,weeks, months to possibly a year or more (not usually in my expierience).
I have also heard of those who breed and raise fry of soft water species in rock hard water ,but these reports are far fewer than I would feel comfortable with if considering the same.
Other's set up species specific tanks ,where adjusting water chemistry to suit the fish is performed but it is much more labor Intensive than suits me .
I have way more success with far fewer problems,by selecting fish that will do well with the water I have from the tap rather than trying to adjust the water to suit the fish, or by hoping that fish will survive in water 's perhaps outside their comfort zone, as opposed to living out long healthy life and hopefully dying of old age. (opinions vary)
